Thanks, Mike.

This seemed like a good hint/possible solution.
Another though has just occurred to me also..  If you use session
variables, you can store the search term in the session, and since the
browser will re-post on reload, if $_POST and your session variable contain
the same search term, its possible (likely?) that it was a reload rather
than a new search, then don't do the search. Not sure if this is helpful,
However, when I tried
start session
put "test" into $_SESSION["keyword"]
put $_SESSION[keyword]
stop session
and the server returned the error

file "/home/pba/public_html/"
  row 2, col 1:

This snippet is at the very top of the page, so row 2 is "start session."

Am I misundertanding the syntax of 'session'?
