Use the form below to search
the NASACT web site for documents containing specific
words or a combination of words. The text search engine
will display a weighted list of matching documents, with
better matches shown first. 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'
