Forum OpenACS Q&A: GeneralComments not getting in search_indexer queue

When I add GeneralComments to an html page, the comments don't get added to the search_indexer queue. The new comments are not searchable then. The search_indexer runs every 30 secs but I don't see the GeneralComments get queued in search_observer_queue table. How do I fix this so my GeneralComments get indexed at some point?!
Thanks.
