4 Phrase SearchingChapter overviewThis chapter describes how to perform phrase searches within the OCLC® cataloging service. Phrase searching is available in the OCLC interfaces as shown below:
4.1 OverviewDefinitionA phrase search allows you to use ordinary language to locate one or more authority records for:
The records can be used as an established heading or as a reference. A phrase search uses the initial words of name, title, or subject headings as a search text. The system matches the text, character by character, against the characters of the terms in the index you selected and displays the phrase or the closest matching phrase. A phrase search allows you to view all established headings and references in the authority records and to retrieve every authority record for a phrase. Access points, indexes, and index labelsThe system indexes certain types of information (e.g., personal names, corporate names, control numbers, subjects) in authority records. Each type of indexed information is an access point. Each access point has an index label. An index label indicates within which index you want the system to search.The system selects the corresponding index and matches your text against the index entries to retrieve matching record(s). Search resultsThe result of a phrase search is a series of increasingly specific lists (also called indexes). The number of lists you work through depends mainly on the number of records you retrieve in the initial list. In CatME™ and Passport this initial list is called the Root Index. In Connexion™ browser it is called Browse Results. The various phrase search paths to authority records are shown below.
The different forms of results are described more fully in chapter 8, Viewing Search Results. back to top4.2 Constructing Phrase SearchesTo construct a phrase search, you must perform these steps:
The order in which you perform these steps varies depending upon which OCLC® interface you are using, and whether you are using the mouse or the keyboard. Connexion browserYou perform a phrase search in the Connexion browser using the Browse Authorities screen. Use of the Browse Authorities rather than the Search Authorities screen identifies this as a phrase search to the OCLC Connexion software.
Connexion clientYou perform a phrase search in the Connexion client using the Browse Authority File dialog box. Use of the Browse Authorities dialog box rather than the Search Authorities dialog box identifies this as a phrase search to the OCLC Connexion software.
CatMEYou perform a phrase search in CatME via the Search OCLC Online window.
The remaining fields in the window are not used in a phrase search. Note: Phrase search is not available in batch mode. PassportYou perform a phrase search in Passport by entering a Scan (sca) command at the Home position with the Authority File selected.
back to top 4.3 Index LabelsThis table shows the index labels used in phrase searches. Note that some access points that are valid for OCLC Connexion are not available in CatME or Passport.
* Use index label co or su to get geographic information. ** Although MARC 21 has established tags 155/455/555 as genre form headings, LC has yet to establish any genre/form terms for the OCLC index label ge. This table shows phrase search examples for index labels in each interface.
* Use index label co or su to get geographic information. back to top4.4 Rules for Phrase SearchesThe general rules apply to all types of phrase searches. Specific rules for subjects, personal, corporate and conference names, and titles follow the general rules. General rulesYou can enter up to 128 characters in a phrase, but you do not need to enter the entire phrase. Because phrase searching is based on a character-by-character match, search techniques such as truncation, character masking (wildcards) and Boolean operators cannot be used. Characters included
Characters excluded
Characters substitutedUse the substitute instead of the character.
Characters converted to spacesYou may include or exclude the following characters. If you exclude them, enter a space in their place. If you include them, the system converts them to a space. The system compresses multiple spaces to a single space.
CommasUse with inverted headings from subfield a for tags 100, 150, and 151. In other situations, substitute a blank space. Characters deletedYou may include or exclude the following characters. If you exclude them, do not enter a space in their place. If you include them, the system deletes them and closes up the space.
Use with inverted headings from subfield ‡a for tags 100, 150, and 151. In other situations, substitute a blank space. Headings with parenthesesInclude the parentheses in the search text.
StopwordsThere are no stopwords with phrase searches. Initial articlesInclude the initial article in your search for the following types of headings:
Initial articles are unlikely in established headings for topical subjects, corporate and conference names, and uniform titles. A multilingual list of initial articles to omit is available on the OCLC Web site. Since system indexing of initial articles depends on how the heading is input, search with and without the initial article to confirm the existence of the heading. Personal namesYou can search for personal name headings from all records with LCCN prefix n, no, nr or nb and tags 100, 400, or 500. See appendix D, Indexed Fields and Subfields, for complete tag, field and subfield information. Personal names used as subjects. Search for personal names used as subjects using a subject search (index labels su or LCSH) if the personal name is in Library of Congress Subject Headings (LCSH).
Heading order. If the heading is inverted, enter the comma in your search. If the heading is in direct order, do not enter a comma.
Partial date information. Enter partial date information in the search to find a specific name.
Pseudonyms and other common names. These systems gather pseudonyms and other common names by indexing tracing fields (4xx and 5xx). You can search for pseudonyms and common names using a personal name search. Corporate namesYou can search for corporate name headings from all records with LCCN prefix n, no, nr or nb and tags 110, 151, 410, 451, 510 or 551. See appendix D, Indexed Fields and Subfields, for complete tag, field and subfield information. Corporate names used as subjects. Search for corporate names used as subjects using a subject search (index labels su or LCSH) if the corporate name is in Library of Congress Subject Headings (LCSH).
Direct word order and parentheses. Enter corporate names and subbodies of corporate names in direct word order. If the heading contains parentheses, include the parentheses in your search text.
Geographic terms used as corporate names. You can search for geographic terms under corporate names (jurisdictional use). The system includes root geographic terms (x51 ‡a and ‡b) as corporate names and subjects.
Earlier, later and variant corporate names. These systems gather earlier, later, or variant corporate names by indexing tracing fields (4xx and 5xx). You can search for these names using a corporate name search. Conference namesYou can search for conference name headings from all records with LCCN prefix n, no, nr or nb and tags 111, 411, or 511. See appendix D, Indexed Fields and Subfields, for complete tag, field and subfield information. Conference names used as subject headings. Search for conference names used as subjects using a subject search (index labels su and LCSH) if the conference name is in Library of Congress Subject Headings (LCSH). Direct word order. Enter conference names and subbodies of conference names in direct word order. If a heading contains parentheses, include the parentheses in your search text
Earlier, later, and variant conference names.
Error processing SSI file TitlesYou can search for title headings from all records with LCCN prefix n, no, nr or nb and tags 130, 430, or 530 and title information (subfield ‡t and following) in any other heading field (x00, x10, x11). See appendix D, Indexed Fields and Subfields, for complete tag, field and subfield information. Titles used as subjects. Search for titles used as subjects using a subject search (index labels su and LCSH) if the title is in Library of Congress Subject Headings (LCSH).
Direct word order. Enter titles in direct word order. If a heading contains parentheses, include the parentheses in your search text.
Series title changes. These systems gather series title change information for title headings by indexing tracing fields (e.g., 430 or 530). You can search for series title change information using a title search. Subjects— topical, name, titleYou can search for headings from all LC subject heading records (records with LCCN prefix sh and sj), names (personal/corporate/conference), or titles used as subjects, and all topical subject headings from name authority records. Examples:
Inverted terms and names used as subjects. Include the first comma in the search text.
Geographic terms used as subject headings. You can locate geographic terms used as subject headings (geographical use). The system includes root geographic terms (x51 ‡a and ‡b) for both corporate and subject searches. Note: When using OCLC Connexion, the index labels Topical Phrases and Geographic Names do not produce identical results. Broader related subject headings. These systems gather broader subject headings by indexing tracing fields (i.e., 550). SubdivisionsYou can search for subdivision headings from all records with LCCN prefix sh, sj, n, no, nr or nb. See appendix D, Indexed Fields and Subfields, for complete tag, field and subfield information. Inverted terms and names. These are not used as subdivision headings. ReferencesYou can search for reference headings from all records with LCCN prefix sh, sj, n, no, nr or nb. See appendix D, Indexed Fields and Subfields, for complete tag, field and subfield information. Note: CatME and Passport do not provide a separate index label for reference headings. When phrase searching for a reference heading, you must use one of index labels: pn, co, cn, su, sc, ti. Inverted terms and names used in references. Include the first comma in the search text.
Children's subjectsYou can search for children's headings from all LC subject heading records with LCCN prefix sj. See appendix D, Indexed Fields and Subfields, for tag, field and subfield information. Examples:
4.5 Error Messages/Revising SearchesOCLC ConnexionBecause the system compares the search text character-by-character against the characters of the terms in the index you selected, incorrect phrase searching generates no error messages. If you accidentally enter an index label as part of the search text, the system treats the label as part of the search text. Example: The text: ti little women with the index label Titles yields these results, which all begin with the string ti li:
