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'
