  1. My AltaVista:Adventures with Advanced Keyword Mary Strouse MAIUG 4 October 25, 2002

  2. AVS Toolbox • Advanced Keyword Fundamentals • Basic Decisions: Screens, Segments & Limits • The Fine Print: WWWOptions, Tokens, Javascript • Advanced staff searching MAIUG 10/25/02 MMS

  3. Why Advanced Keyword? • Speed – faster results, faster indexing • Phrase searching • Segmentation – keyword in title, etc. • Cross-index searches – Author/Title, Subject/Genre, etc. • Wildcarding MAIUG 10/25/02 MMS

  4. Why Advanced Keyword? • Pre-search limits & sorts • Bells & whistles • Proximity operators (near & within n), • Relevance ranking (title, then author, then subject!) • Keyword highlighting MAIUG 10/25/02 MMS

  5. What Hasn’t Changed • Only indexed fields are searched • Result is a list of titles • No cross-references • Limit on retrieval (32,000 vs. 5,000 “bib record entries”) • Keyword synonyms list MAIUG 10/25/02 MMS

  6. Cross-Reference MAIUG 10/25/02 MMS

  7. Subject Search Result MAIUG 10/25/02 MMS

  8. Keyword Search Result MAIUG 10/25/02 MMS

  9. Basics: 3 Search Screens (+1) The X,Y and Z of it: X – Advanced Boolean (pre-search limits & sorts) Y – Simple Boolean (w/o limits/sorts) Z – “AltaVista Style” searching MAIUG 10/25/02 MMS

  10. “AltaVista” Searching • Broader search (default “Or”) • Use + and – to include/exclude • Relevance ranking of results • No segments, limits, or boolean operators • Auto wildcarding to end of word MAIUG 10/25/02 MMS

  18. Custom Limit Using 006 MAIUG 10/25/02 MMS

  29. AVS WWWoptions • ASSEARCH (Release 2000 Update D) (Replaces ASTRUNCATE) 1 Change “no hits” search to "AND" 2 Change to "OR" 3 Strip off field limits … Etc. • Coming: option to restore “and”default (Rel 2002 Phase 3) MAIUG 10/25/02 MMS

  30. AVS WWWoptions • AVS_RELEVANCE_FORMAT= • Controls display -- text vs. graphics (also IMAGE_AVS#= ) MAIUG 10/25/02 MMS

  31. …and a System Option      A = Alphabetical     D = Date    R = Relevance First code is the default (controls in Telnet, Millennium, & when sort undefined). MAIUG 10/25/02 MMS

  32. Tokens Take Over AVS Required Tokens: • <!--{msg}--> Error message Needed to generate “no hits” message • <!--{search}--> creates search input box MAIUG 10/25/02 MMS
