Make a form with action="GET" and try the search you want. You'll
want to look for the &words=... bit, which is the user's query.

No limit, but if you're using the GET method, many servers have a
limit for the length of URLs.

Well that's how the expression is parsed... I hate to use the term
"guarantee" since it feels like I'm signing some legal form, but
that's how it works.

It'll probably slow things down--the more terms in the query, the
more database lookups must be performed at present. But whether this
has a real-world performance impact depends a lot on the setup.
