| Text Search Advanced Help Click the "BACK" button on your browser to return to the page you came 
from! Use the text search engine to search documents in the web containing specific 
words or combinations of words. The text search engine will display a list of matching documents, 
with more current 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 shown below, along with examples.Query Language 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 and not retrieval 
    finds documents containing 'information' but not 'retrieval'
(information and not retrieval) and WAIS 
    finds documents containing 'WAIS', plus 'information' but not 
    'retrieval'
web* 
    finds documents containing words starting with 
'web'
