Help on Search

Search for documents in this web site using keywords 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.

The text search engine allows queries to be formed from arbitrary Boolean expressions containing the keywords AND, OR, and NOT, and grouped with parentheses.

this search engine finds documents containing 'blue' or 'sky'

blue not sky
finds documents containing 'blue' but not 'sky'

(blue not sky) and cloud
finds documents containing 'cloud', plus 'blue' but not 'sky'
