Additional context

In the orgmode manual section linked above, it appears that they do a regex search on the actual content of a headline. My intended use case is actually detailed here, and seems to involve expanding a regex when searching for a tag match. I'm not exactly sure where that behavior is documented, but it would be nice to have such a filter.

I may be able to help implementing this if given someplace to start.
