Title: The Search for the Holy Grail: Why OneStop Searching is Both Essential and Hopeless


1
The Search for the Holy Grail Why One-Stop
Searching is Both Essential and Hopeless

The Issue
  • Most users do not care where the information they
    need comes from, or who provides it (remember,
    only librarians like to search)
  • Nor should they have to
  • But our systems presently require them to know
    these things
  • How can we create systems that minimize what the
    user needs to know to get what they want?

The Integration Engine
  • Parse the query for each database, formulating
    the best possible search for that resource
  • Sort, organize, and de-dup the results
  • Rank according to perceived relevance
  • Be fault-tolerant (does the best it can with what
    its given)
  • Offer additional ways to filter or display the
    results

17
Challenges
  • Target selection and weighting
  • Response time
  • Unresponsive targets
  • Screen scraping
  • Presentation of results
  • Merging
  • De-duping
  • Ranking
  • Further options
  • Search within results
  • Filtering

Strategies to Consider
  • Focused cross-database searching
  • A few good things
  • By subject area
  • Cooperative development (e.g., the ARL Scholars
    Portal project)
  • Press vendors for an option to receive search
    results as an XML data stream

21
Why Will it Never be Fully Achieved?
  • Market forces
  • The pace of change
  • Complexity of systems and diversity of data,
    metadata, terminologies, etc.
  • Organizational, political, and cultural realities
  • Therefore, our search for the one-stop search
    solution is destined to fail as did the knights
    in their quest for the Holy Grail

22
But is it Worth the Quest?
Certainly! Even minor gains will be better than
what we have now! Godspeed!
