Indexing custom WPC forms

Hello All-

I have a WPC site which uses custom forms for much of it's content. For some reason, none of the content within these forms gets indexed. Search results return only the page title and the message "No document excerpt available". If the same content is placed in the delivered WPC forms, and stored in the same site structure in KM, the contents are indexed correctly. The pages are also custom.

Can someone tell me what I need to change in order to make the content in my custom forms available to the indexer?

thanks
