why advanced keyword
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

why advanced keyword1
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

what hasn t changed
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

basics 3 search screens 1
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

altavista searching
“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

basics 4 segments
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 MMS

basics choice of fields
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 )

basics choice of limits
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 MMS

custom limits good and bad
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

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 MMS

avs wwwoptions1
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)

avs wwwoptions2
AVS WWWoptions
  • AVS_RELEVANCE_FORMAT=
  • Controls display -- text vs. graphics

(also IMAGE_AVS#= )

and a system option
…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

tokens take over
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

no hits message
“No hits” Message

MAIUG 10/25/02 MMS

what else required tokens do
What [else] Required Tokens Do

<!--{search}--> also:

  • Preserves search criteria on “modify search”
  • Triggers color highlighting of keywords

MAIUG 10/25/02 MMS

the java jive
The Java Jive

Javascripts library on CSdirect:

  • Expand “no hits” search to other catalogs/scopes (various versions)
  • Search-builder (coming soon?!)
  • [Your idea here]

  • Segments (a:, t:, s:, n:) &

variable limits (publisher, genre)
