+Provide a sane syntax for date ranges. First, we don't want to require
+both endpoints to be specified. For example it would be nice to be
+able to say things like "since:2009-01-1" or "until:2009-01-1" and
+have the other enpoint be implicit. Second we'de like to support
+relative specifications of time such as "since:'2 months ago'". To do
+any of this we're probably going to need to break down an write our
+own parser for the query string rather than using Xapian's QueryParser
+class.

Add support for files that are moved or deleted (which obviously need
to be handled differently).
(tag-name, search-specification). The database is responsible for
ensuring that the virtual tag is always consistent.
+Think about optimizing chunked searches (max-threads > 0) to avoid
+repeating work. That would be saving state from the previous chunk and
+reusing it if the next search is the next chunk with the same search
+string.
