My site uses framesets, with $$ViewTemplates usedto format the views. When I
created the subform and included it in one of the view templates, I found that
removed the Notes Field from my subform.
The search actually ran, however it was continually searching for the text
"undefined" (pretty obvious that there was an error happening in there
somewhere!) and finding the document in my database that contained that text.
Not entirely sure how what I'm doing is drastically different to anyone else
here, but it just drove me crazy for a few minutes while working that out, so I
thought I'd post in case anyone else has their site setup in a similar fashion.
