apt-xapian-index now comes with a query tool
I've just uploaded a new version of apt-xapian-index to unstable. Now it comes with a little query tool called axi-cache.
You can search this way:
axi-cache search foo bar baz facet::tag sec:section
In fact, you can use most of the things described here.
You can then say
axi-cache more to get more results, or
axi-cache again to
retry a search, or
axi-cache again wibble wabble to add keywords to the

I need to thank Carl Worth who, with notmuch, reminded me that if I just build a nice interface on top of Xapian's query parser I go quite a long way towards making a Xapian database extremely useful indeed.

Just for reference, this is the command line help:
$ axi-cache help Usage: axi-cache [options] command [args] Query the Apt Xapian index. Commands: axi-cache help show a summary of commands axi-cache search [terms] start a new search axi-cache again [query] repeat the last search, possibly adding query terms axi-cache more [count] show more terms from the last search Options: --version show program's version number and exit -h, --help show this help message and exit -s SORT, --sort=SORT sort by the given value, as listed in /var/lib/apt- xapian-index/values --tags show matching tags, rather than packages --tabcomplete=TYPE suggest words for tab completion of the current command line (type is 'plain' or 'partial')
If you install the package for the first time, you may need to rebuild the
index by running
update-apt-xapian-index as root before using axi-cache.
