Site Search Form
Use the form below to search for documents in the PFS
web containing specific words or combinations of words. The text search engine will
display a weighted list of matching documents, with better matches shown first. (You
may need to scroll down to see results.) Each list item is a link to a matching document;
if the document has a title it will be shown, otherwise only the document's file name is
displayed.
A brief explanation of the query language is available, along
with examples.
The text search engine allows queries to be formed from arbitrary Boolean expressions
containing the keywords AND, OR, and NOT, and grouped with parentheses. For example:
- information retrieval
- finds documents containing 'information' or 'retrieval'
- information or retrieval
- same as above
- information and retrieval
- finds documents containing both 'information' and 'retrieval'
- information not retrieval
- finds documents containing 'information' but not 'retrieval'
- (information not retrieval) and WAIS
- finds documents containing 'WAIS', plus 'information' but not 'retrieval'
- web*
- finds documents containing words starting with 'web'
