It looks to me like you're on the right track.

Try testing whether the session variable is set before you set it.  
That will tell you if it is a new request to the search page or a  
subsequent modification of search terms.

The PHP manual is great. Two thing I always do when I'm learning  
about a new function I've never used before:

1) Check the manual for other related functions
2) Read the user comments and see if there are any examples of what I  
am trying to do with the function. There usually are.

Cheers,
