Are you saying that your database is corrupted by the bug which was
fixed in 1.0.8?
If so, you should be able to make a valid database from it using
copydatabase (one of the xapian-core examples).
You can remove all databases with mention the term "foo" from PHP with:
There's no built-in way to remove all mentions of a term without also
removing all the documents which mention the term - you'd have to
iterate all the documents indexed by the term, get each document, call
Document::remove_term() and then WritableDatabase::replace_document().
