6 Keyword and Command Line Searching in OCLC ConnexionChapter overviewThis chapter describes keyword and command line searching using the OCLC ConnexionTM interfaces. Keyword and command line searching are available in the OCLC® interfaces as shown below:
6.1 Overview of Keyword SearchingDefinitionKeyword searching allows you to use ordinary language to:
The Search screen contains five text boxes. You may use one or more words in each box for keyword search. Be sure to select the correct index for word(s) you enter. Keyword searching is available only in OCLC Connexion™. 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). For a record to be retrieved by a keyword AND search, it must contain all the search terms specified. Search resultsThe results of a keyword search may be either a list of brief entries or a single authority record.
The different forms of results are described more fully in chapter 8, Viewing Search Results. back to top6.2 Constructing Keyword Searches (Connexion Browser)To construct a keyword search you must perform these steps:
The order in which you perform these steps varies depending upon whether you are using the mouse or the keyboard. Single termTo search for a single term, use the Keyword Search area of the Search Authorities screen. Use of the Keyword Search area identifies this as a keyword search in the Connexion browser interface.
Note: Since Personal Names is automatically highlighted as the first index label in the list, if you type a personal name as your initial search you can press < Enter > immediately. Multiple termTo combine multiple terms in a search in Connexion browser:
Example 1: This search is limited to all works by Mark Twain that include Finn in the title. Results include records for or related to the Adventures of Huckleberry Finn only.
Example 2: This search retrieves all works by Mark Twain except those that include Finn in the title. Results include everything except the Adventures of Huckleberry Finn.
Example 3: This search is limited to all works by Mark Twain that include FinnorSawyer in the title. Results include records for or related to the Adventures of Tom Sawyer as well as those for or related to the Adventures of Huckleberry Finn.
6.3 Constructing Keyword Searches (Connexion Client)To construct a keyword search you must perform these steps:
The order in which you perform these steps varies depending upon whether you are using the mouse or the keyboard. Single termTo search for a single term, use the Search Authority File dialog box. Use of the Search Authority File rather than the Browse Authority File dialog box identifies this as a keyword search in the Connexion client interface.
Multiple termTo combine multiple terms in a search in Connexion browser:
Example 1: This search is limited to all works by Mark Twain that include Finn in the title. Results include records for or related to the Adventures of Huckleberry Finn only.
Example 2: This search retrieves all works by Mark Twain except those that include Finn in the title. Results include everything except the Adventures of Huckleberry Finn.
Example 3: This search is limited to all works by Mark Twain that include FinnorSawyer in the title. Results include records for or related to the Adventures of Tom Sawyer as well as those for or related to the Adventures of Huckleberry Finn.
6.4 Keyword Index LabelsThe following tables show index labels that are used with OCLC Connexion keyword searches.
The following table shows keyword search examples for all index labels.
back to top 6.5 Rules for Keyword SearchesPrepositions and articlesOmit all prepositions and articles. A multilingual list of initial articles to omit is available on the OCLC Web site at: < http://www.oclc.org/support/documentation/worldcat/searching/userguide/ >. Example: midsummer night's dream (for title A Midsummer Night's Dream) PhrasesWhen using multiple keywords, the spaces between the words are treated as and operators. Example: The following two searches are equivalent:
Search using variant termsTruncation. To search for the first part of a word, including variant endings, use the asterisk (*). Enter as many characters as you know, then enter an asterisk. Example 1: compu* (as a topical) retrieves subject headings including:
Example 2: reyk* (as a geographic) retrieves subject headings including:
Character masking (wildcards). Use wildcards ? and # to expand a word to include variant spellings, when you know only the first part of a word, or when you are unsure of the correct spelling for part of a word. Question Mark. The question mark (?) retrieves variants of 0 or more characters. Examples: col?r retrieves headings containing both color and colour int?net retrieves headings containing both internet and intranet b?nd retrieves headings containing bind, blind and bound. Number Sign. The number sign (#) retrieves variants of exactly one character. Example: wom#n retrieves headings containing both woman and women. b#nd retrieves headings containing bend, bind and bond. back to top6.6 Overview of Command Line Searching (Connexion Browser)DefinitionCommand line searching provides the ability to enter a phrase search from the Connexion browser Search Authority File without changing to the Browse Authority File screen. 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). For a record to be retrieved by a search using the Boolean operator AND, it must contain all the search terms specified. Search resultsCommand line keyword. The result of a command line keyword search may be either a list of brief entries or a single authority record.
Command line phrase search. The result of a command line phrase search is an initial list called a Browse Results list, which may lead to a list or brief entries or to a single authority record.
The different forms of results are described more fully in chapter 8, Viewing Search Results. back to top6.7 Constructing Command Line SearchesTo construct command line searches:
Single term keywordTo search for a single keyword, use the Command Line Search area of the Search Authorities screen. Use of the Command Line Search area identifies this as a keyword search in the Connexion browser interface.
Multiple term keywordTo search using multiple keywords, use the Command Line Search area of the Search Authorities screen. Use of the Command Line Search area identifies this as a keyword search in the Connexion browser interface.
Example 1: This search is limited to all works by Mark Twain that include Finn in the title. Results include records for or related to the Adventures of Huckleberry Finn only. You enter: pn:twain and ti:finn Example 2: This search retrieves all works by Mark Twain except those that include Finn in the title. Results include everything except the Adventures of Huckleberry Finn. You enter: pn:twain not ti:finn Example 3: This search is limited to all works by Mark Twain that include FinnorSawyer in the title. Results include records for or related to the Adventures of Tom Sawyer as well as those for or related to the Adventures of Huckleberry Finn. You enter: pn:twain and ti:finn or ti:sawyer Phrase searchEntering a command line phrase search requires the Scan command (sca) as well as an index label and search term(s). Note the following:
back to top 6.8 Command Line Index LabelsThis table shows the index labels used in command line phrase searches. Note that some access points that are valid for OCLC Connexion are not available in CatME or Passport.
* 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 Command Line index labels.
back to top 6.9 Rules for Command Line Keyword 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 command line keyword 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 at: 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.
