Understanding InfoHawk Indexes

This guide explores the technical aspects of creating and managing indexes in libraries. Learn about different index types, filing routines, word breaking rules, and index building processes. Discover how direct indexes work and how to make them available for browsing and searching in library systems. Find solutions to common issues and get tips on refining search sets in the GUI OPAC.

  1. Understanding InfoHawk Indexes Technical Background for Libraries Staff Patricia Baird Sue Julich

  2. OBJECTIVES • Tables necessary to create an index • What information is contained in the various indexes • “What happened to my direct indexes?” (the bulls eye icon) • How are some of the indexes different from each other

  3. Tables and More Tables: Background • unicode_to_filing_01_source • Defines how individual characters will file (as themselves, as blanks, as nothing, etc.) • tab_filing • Sets up filing routines (changes specified characters to blanks, change to lower case, compress multiple blanks to a single blank, suppress specified characters, etc.)

  4. Tables and More Tables: Background • tab_word_breaking • Define rules as to what constitutes a word. The basic definition is any character string between two blanks. (suppress periods or commas between single characters – I.B.M.=IBM; 12,000= 12000, etc.) • tab00.eng • Indexes are assigned names and codes. • tab11 • Fields and subfields are assigned to Indexes.

  5. Building the Indexes: A few of the processes • p_manage-01 – Generate word indexes • p_manage_02 – Generate headings indexes • p_manage_05 – Generate direct number indexes • p_manage_17 – Alphabetize long headings; runs through each headings index created • ue_08 – creates headings from AUT library in the BIB library

  6. Direct Indexes • Direct indexes contain unique entries; • Record ID • NOTIS ID • ISBN • Can be searched by: • BROWSE • FIND

  7. Making the Indexes Available • pc_tab_sear.eng • Sets up the order and name displays of indexes available in the GUI OPAC – BROWSE and FIND • pc_tab_find.eng (two versions) • One for cataloging module • One for admin modules • pc_tab_scan.eng (two versions) • One for cataloging module • One of all admin modules

  8. Known Issues • Currently can only search on first 34 characters of a heading (unicode= 2 bytes per character) • Call numbers = best bet are the browse indexes (All or LC) • Some diacritics not filed correctly; if you run across them, re-save the record.

  9. Additional Information • You can now FIND or BROWSE the DIRECT Number indexes, depending upon how we have decided to offer them. • You can refine or cross BROWSE search sets in the GUI OPAC • You can cross a BROWSE result set with a FIND result set.

  10. Additional Information • A FIND search in the GUI OPAC will retrieve all entries, but a FIND search in the other client modules will retrieve up to 100 records. • When using the FIND search in the client modules other than GUI OPAC, you can combine indexes to search (e.g., search of a title and an author at the same time.
