While implementing the attachment indexing mechanism, we (febbraro, robertDouglass and I) stumbled across a problem: how to store the attachment text?
It would be easily possible to just append it to the "text" field or add a new, multi-valued field or both. But then it would be impossible to distinguish the place of occurence of the term at search time, which, unfortunately, is a requirement, since the attachments should appear directly in the search results, not just links to the nodes containing them.
