[Xapian-discuss] Phrase Searching

RTFM :(

The rest of the system is going pretty well, there's some danger of going
live with it.

Thanks Olly

Did you index with positional information?  If there's no positional
information in the database then PHRASE is converted to AND (which seems
more useful than matching nothing, which is what we used to do...)

The delve tool in the examples subdirectory is a good way of checking
this sort of thing.
