Ambox notice.png This article is currently a draft.

This article provides an introduction to Hamnet's search capabilities, and some tips for making the most of them.

Introduction

This article is walks through the search options available in the Basic and Advanced Search tabs, and discusses some methods of searching and narrowing down searches. It is meant to supplement the detailed instructions already available on Hamnet, rather than duplicate effort. Search help is available below both the Basic and Advanced Search areas. Click on each search name to open documentation with tips for using search effectively.

To learn more about the parts of the MARC catalog records that each option searches, refer to the List of keyword search fields in Hamnet and their associated MARC codes.

General search tips

  • When doing call number searches, follow the punctuation and spacing guidelines for each type of call number to ensure the best search results. This is especially important when searching for manuscript call numbers. If you are not getting many results, try shortening the call number (i.e., search for "PR2796 .F6" instead of "PR2796 .F6 C2 1924 Sh.Col.").

Keyword searching vs. browse search

All search options in Hamnet are either keyword searches or browse searches. Both types of search take a sequence (or sequences) of characters - i.e. word(s) - that the searcher inputs and look for matches in the Hamnet database.

A keyword search is the more straightforward of the two: it looks for the sequence (or sequences) of characters entered, either in a specified field of each catalog record, or anywhere in each catalog record. It will give you a list of the records in which the sequence of characters appears.
A browse search looks for the search term(s) in specified fields in each catalog record, then shows you where the search terms do (or would) appear within an alphabetical list of the terms that have been entered into that field by catalogers (usually drawn from controlled vocabularies). From there, you can click on your search term (or any other heading) to see records that include it, or see that there are no records which use that specific term. Headings shown as underlined red text are in use (the number of records in which they are used is indicated in the column to their left); headings in black text are not used in any records, but may provide useful cross-references to other headings which are.

Notice that some headings have a red asterisk at their far left. Clicking on the asterisk will take you to suggestions for related headings, such as authorized forms of names, or earlier or later forms of names.

Basic Search tab

The Basic Search tab includes thirteen search options, grouped thematically. These include both keyword searches and browse searches. Notice that some search options have an asterisk next to their labels: this indicates that you can set limits (see the search limits section below) to narrow the parameters of your search. It also means, functionally, that these are keyword searches (you cannot set limits on browse searches). Basic Search tab search options.JPG

Name Browse - looks for your search term(s) in a list of name headings used in records
Author/Creator, Sorted by Title - looks for your search term(s) in a list of main author headings used in records
Title (Keyword Phrase) - looks for your search term(s) anywhere in any title fields
Title (Left-Anchored) - looks for your search term(s) at the beginning (reading from the left) of any title fields
Journal title (Keyword Phrase) - looks for your search term(s) anywhere in any title fields in periodical catalog records
Series/Uniform Title Browse - looks for your search term(s) in a list of title headings used in records
Subject & Form/Genre Browse - looks for your search term(s) in a list of subject and form/genre terms used in records
Form/Genre (Keyword Phrase) - looks for your search term(s) anywhere in any form/genre fields
Call Number (Left-Anchored) - looks for your search term(s) at the beginning (reading from the left) of any call number field
Call Number (Browse) - looks for your search term(s) in a list of call numbers used in records
Publication/Creation Date - looks for your search term(s) - in this case, usually a number - in any publication or creation date fields
Keyword Any Bib Field (Relevance-Ranked) - looks for your search term(s) anywhere in any record
Expert Search (use index codes and operators) - uses index codes and Boolean operators to combine multiple searches; see Expert Search section below

Basic Search tab defaults

  • The Basic Search tab opens with the Name Browse search highlighted; double-check that you have highlighted the correct search option before starting your search.
  • Basic Search defaults to an OR search, not an AND - i.e., if you enter multiple search terms, it will search for records that contain any of them, not all of them. If you want to search using multiple search terms, it's better to use the Expert Search option or the Advanced Search tab.

Advanced Search tab

The Advanced Search tab has three sets of boxes and menus that enable users to build a relatively complex search. Each line has a search box with a drop-down menu immediately to its right, and another drop-down menu at the far right which includes twenty-one search options. The drop-down menus next to the search boxes allow you to specify how the search terms in each box should be treated: "all of these" (search for records that contain all terms), "any of these" (search for records that contain at least one term, but not necessarily all), or "as a phrase" (search for records that contain your terms in the exact order you entered them). Each line can be combined with the "AND," "OR," or "NOT" radio buttons in between them.

You can set limits on any of the search options. Since all Advanced Search options are keyword searches, each one will return a list of records matching your search (or indicate that no records match your search).

Use Advanced Search to look for very specific items, or to help narrow down broad searches. For instance, if you are looking for early modern works on medicine, you could combine a subject search for "medicine" with a call number search for "STC," or a form/genre search for "Early works to 1800."

Keyword Any Bib Field - looks for your search term(s) anywhere in each record
Title - looks for your search term(s) in any title fields in each record
ISBN - looks for your search term(s) in the ISBN field of each record
Name - looks for your search term(s) in any name heading field (not just authors) in each record
Subject - looks for your search term(s) in any subject heading field in each record
Published/Created Date - looks for your search term(s) in any publication/creation/production date field in each record
Publisher/Printer Name - looks for your search term(s) in the publisher/printer/producer field in each record (note that this searches the name as it appears on the item, not necessarily its authorized form)
Folger Copy Notes - looks for your search term(s) in any copy-specific notes in each record
Material Type [GMD] - looks for your search term(s) in the GMD field in any record
ISSN - looks for your search term(s) in the ISSN field of each record
Published/Created Place - looks for your search term(s) in any publication/creation/production location field in each record
All Notes - looks for your search term(s) in any note field in each record
Bibliographic Citation - looks for your search term(s) anywhere in the reference citation field in each record
Series - looks for your search term(s) in any series title field in each record
Physical Description - looks for your search term(s) anywhere in the physical description field in each record
Holdings Record - looks for your search term(s) anywhere in the holdings record (which gives information about the location of the item, its call number, etc.)
Size/Format - looks for your search term(s) anywhere in the size subfield in each record (which may contain measurements such as "22 cm," formats such as "8vo," or both, such as "14 cm (12mo)")
Form/Genre - looks for your search term(s) in any form/genre field in each record
Edition Statement - looks for your search term(s) anywhere in the edition statement field of each record
Exhibition history - looks for your search term(s) anywhere in the exhibition history field of each record

Advanced Search tab defaults

  • The Advanced Search tab opens with the Keyword Any Bib Field search option in all three drop-down menus.
  • Advanced Search defaults to AND searches - the radio buttons for "AND" are automatically selected, and the center drop-down menu opens with "all of these" selected. If you enter multiple keywords in a single search box, it will search for records that contain all of them, not just any of them.

Search limits

The Set Limits option appears in both the Basic and Advanced Search tabs, in the bottom right corner of the main search area. Clicking the link leads to a separate dialogue page. (NOTE: if you have already entered search terms or changed the default settings, navigating to the Set Limits dialogue will erase them.)

Set Limits page.JPG

There are five limits that you can set to help narrow your search. You can select multiple options from each menu by pressing the Crtl key while clicking on them, or select a range of options by pressing the Shift key while clicking.

  • Language - language of an item
    • Note: not all catalog records include a language designation (for instance, graphic materials)
  • Location - location of an item within the Folger
  • Date - enter a specific date, or a range
  • Item type - broad format categories which are similar but not identical to GMDs
  • Place of publication - country where an item was published


Once limits are set in either Basic or Advanced Search tab, they will remain in place for all future searches done within that session. You can get rid of limits by clicking Clear Limits (next to the Set Limits link in the bottom right corner of the main search area), or by leaving your search session (by closing the browser tab or navigating to a different webpage).

Boolean search and wildcards

Boolean search

Boolean search uses "operators" such as "AND," "OR," and "NOT" to narrow or broaden a search. Its concepts are based on Boolean logic.

AND will search for records that contain all terms
OR will search for records that contain any terms
NOT will search for records that do not contain particular terms

You can use Boolean operators in multiple areas of Hamnet:

  • Enter them manually in the Expert Search option of the Basic Search tab
  • Select "AND," "OR," or "NOT" radio buttons to combine search boxes in the Advanced Search tab.
  • Use the relevant drop-down menu in the Advanced Search tab to specify "all of these" (i.e. "AND") or "any of these" (i.e. "OR").

Wildcard characters

Wildcard characters are generally used to account for uncertainty in a search, by substituting for one or more characters. For instance, if you're uncertain whether an item uses "theater" or "theatre," you can search for both by substituting wildcard characters for the er/re. Wildcards can be used with any keyword search in Hamnet, and you can use multiple wildcards in the same search, or even in the same search term.

? will look for an unspecified number of characters. It is most useful when used at the beginning or end of a search term to look for words that include that term.
theat? will return records with either "theatre" or "theater," but also other words such as "theatrical," "theatergoer," etc.
% takes the place of exactly one character. It is more useful for spelling variations, such as the theater/theatre example, or for finding i/j/u/v transcriptions. However, % cannot account for characters that are not there.
theat%% will return records containing "theatre," "theater," or any other words with two characters after "theat," such as "theatrum" or "theatra"
Shak?pe?r% will return records containing a variety of spellings of Shakespeare (using ? to substitute for one or more characters inside the word), but since the last wildcard is %, it will not return "Shaksper."

Expert Search

The Expert Search option on the Basic Search tab allows you to combine searches of multiple fields by using their search codes and Boolean operators. The search codes are four-letter abbreviations for the keyword searches available on the Advanced Search tab. Select Expert Search, and type the search code and the term(s) you want to search for. Surround your terms with quotation marks to search for them in a specific order (i.e. "shakespeare william," or "william shakespeare"), and combine multiple searches using Boolean operators AND, OR, or NOT. You can enter search codes and operators in either lowercase or uppercase. You can also nest searches by using parentheses. Each search word needs to be preceded by a distinct search code, and multi-word search terms should be surrounded with quotation marks - Expert Search otherwise treats each word as a generic keyword search.

245h realia not gkey shakespeare - finds records for realia objects that are not directly associated with Shakespeare
NKEY garrick AND (KGNR "legal instruments" OR KGNR "legal documents") - finds records for items associated with David Garrick (or any other Garricks) that have the genre terms "legal instruments" or "legal documents"

Expert Search defaults

  • If you do not enter a search code, Expert Search defaults to a standard keyword search.
  • Note: the search box has a limit of 100 characters.
