Remote searchers will crawl your site and store your info in an index on
their server. When someone enters a query in the search form on your site,
the link points at the search engine host. It receives the query, does the
lookup in the index, formats the results, and sends them back in an HTML form
with links directly to the pages on your site.
Some services provide simple, straightforward searches, while others offer
powerful advanced search functions such as proximity operators (NEAR), date-range
searching, and control of the results formats. Some are free and supported
by advertising, others charge by the page, by the search or monthly.
Remote search services do not require any programming or local access to
the web server. They act like standard robot spiders, following links on your
site, rather than using the local file system. For hosted sites with limited
server access, these services are an excellent option.
