exclude custom table from indexing

I have a form in wordpress which takes some search parameters and returns matching records from a custom table in mySQL.

Now, when I do a search through Relevannsi I’m getting these records in my resultset. And the results are formatted in exactly the same way as if I was using my search form.

I’d like to prevent this happening. I’ve tried putting both the search parameter form and the form it calls to present the results in the post/page exclusion box but to no avail.

Can some one help me with what settings I need to change?
