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

MAIUG 10/25/02 MMS2 AVS Toolbox Advanced Keyword Fundamentals Basic Decisions: Screens, Segments & Limits The Fine Print: WWWOptions, Tokens, Javascript Advanced staff searching

MAIUG 10/25/02 MMS3 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 MMS4 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 MMS5 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 MMS6Cross-Reference

7 Subject Search Result

MAIUG 10/25/02 MMS8 Keyword Search Result

MAIUG 10/25/02 MMS9 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 MMS10 “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 MMS11 Simple Boolean (Y)

MAIUG 10/25/02 MMS12 Advanced Boolean (X)

MAIUG 10/25/02 MMS13 The Search-builder (X+)

MAIUG 10/25/02 MMS14 Basics: 4 Segments Author (a:), Title (t:) and Subject (s:) –Use same fields as existing indexes Notes (n:) –Fields customizable at setup All fields must belong to at least one segment (… or limit) No custom segments (but….)

MAIUG 10/25/02 MMS15 Basics: Choice of Fields Maximalist approach (default) – includes most 5xx fields Minimalist approach – 505, 520 [& 970 subfields not already included] “Notes” segment can include other fields or subfields (ex. GMD from 245 |h )

MAIUG 10/25/02 MMS16 GMDs in Notes Segment

MAIUG 10/25/02 MMS17 Basics: Choice of Limits Pre-Search Limits can be: Fixed length codes Special fields (006, 008) Variable fields Existing Post-Search limits as default (minus “search as words”) Custom limits allowed

MAIUG 10/25/02 MMS18 Custom Limit Using 006

MAIUG 10/25/02 MMS19 Custom Limits, Good and Bad Variable field limits function like custom segments Pre-search limits are indexed Use caution. Data from limits added to general (unsegmented) search ex. Publisher limit

MAIUG 10/25/02 MMS20 Variable limit in Cross-Index Search

MAIUG 10/25/02 MMS21 Limit Used as Exclusion

MAIUG 10/25/02 MMS22 Variable Limit as Drop-down

MAIUG 10/25/02 MMS23 Publisher Limit

MAIUG 10/25/02 MMS24 “Noise” Retrieval

MAIUG 10/25/02 MMS25 Display WWWoptions KEYWORD_COLOR= Controls color highlighting –On/Off –Color choice –What fields/field groups apply DROP_DOWN= Controls inclusion & order of indexes in the “search widget”

MAIUG 10/25/02 MMS26 Keyword Highlighting

MAIUG 10/25/02 MMS27 Keyword in Search Widget

MAIUG 10/25/02 MMS28 AVS WWWoptions AVS_TAG=XYZ –Determines what search varieties are allowed (Must have search screens to match) –May still choose not to offer all 3 screens in mainmenu –Consider impact on pass-through searches (e.g. Partners, INN-Reach)

MAIUG 10/25/02 MMS29 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 MMS30 AVS WWWoptions AVS_RELEVANCE_FORMAT= Controls display -- text vs. graphics (also IMAGE_AVS#= )

MAIUG 10/25/02 MMS31 …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 MMS32 Tokens Take Over AVS Required Tokens: Error message Needed to generate “no hits” message creates search input box

MAIUG 10/25/02 MMS33 “No hits” Message

MAIUG 10/25/02 MMS34 What [else] Required Tokens Do also: Preserves search criteria on “modify search” Triggers color highlighting of keywords

MAIUG 10/25/02 MMS35 The Java Jive Javascripts library on CSdirect: Expand “no hits” search to other catalogs/scopes (various versions) Search-builder (coming soon?!) [Your idea here]

MAIUG 10/25/02 MMS36 Partners Link from Search Results

MAIUG 10/25/02 MMS37 Pass-through “no hits” Screen

MAIUG 10/25/02 MMS38 Advanced Staff Searching Advanced Keyword in both Telnet and Millennium In Millennium and Telnet Search, default is simple Boolean (Y) search In Telnet staff modules, use command language to specify search (X,Y or Z)

MAIUG 10/25/02 MMS39 Staff Command Line Qualifiers Segments (a:, t:, s:, n:) & variable limits (publisher, genre) Fixed-length limits –mattype:mattypen –lang:langn –branch:branchn Default sort Post-search limiting (not recommended)
