Database Search

Search all databases
Limit Your Results


While searching multiple databases at once can be useful, by definition it's lowest-common denominator searching. None of the advanced search techniques available in individual databases will be available. Some pitfalls to watch out for:

  • Your search results may mix apples and oranges... or, less figuratively, things like articles and dissertations.
  • Subject headings won't be consistent.
  • Databases with full-text searching may be over-represented in your results, simply because they have more words to match on.
  • Relevancy ranking doesn't work well.
