The text search function allows you to search for information
using search terms. Results are measured by a document's score:
the higher the score, the more likely it is that the document will
match the specified search criteria.
Simply type a number of words (separated by spaces) into the
search field and choose "Go." Pages that contain
all of your search terms will be displayed. They will be ranked
by the frequency and positional relevance of your search terms.
