Search engines
provide
the ability to search for text strings or words within large collections
of text and addresses.
These collections are
automatically generated by
robots
(or spiders)
which mechanically traverse the Web and collect text.
The text is automatically
converted by an indexing engine
to a format which can be efficiently processed by a
search engine.
