beagle-query configurability

[Jonathan-72]

Hello folks,

I see that there has been some discussion in the past regarding the
maximum number of hits returned by beagle-query.  I'd like to throw in
my 2c worth with the following comments:

The hard-coded limit of 100 hits is the single most annoying thing in
the whole of beagle, which is otherwise a wonderfully useful tool for my
work.  I regularly get messages like 'Too many matches. Showing latest 6
of total 711'.  These six hits are often not enough to find what I was
looking for.  I can use beagle-search, but as it shows no preview of the
files its results aren't of much use to me either.

First of all, if beagle-search can't return all the matches, then I
would like to be able to choose whether I get the most relevant, the
most recent, the oldest, etc.  As a suggestion, it could use the same
criteria as the 'Sort' option.

Secondly, I would like to be able to get more than 100 matches. Well
actually 100 would be OK if I could get the 100 most relevant, but (to
take the case above) 6 is not.

I'm not averse to a bit of code-hacking but I'm no python programmer and
don't have the time to reverse-engineer the project. If someone could
point me in the right direction to make these changes I'd be happy to do
some work on it.

Cheers,
Jonathan

Which version are you running ? If you are running 0.3.9 (latest),
then I would suggest a complete reindexing of all the files
$ beagle-shutdown
$ rm -rf ~/.beagle/Indexes/FileSystemIndex
$ beagled

There was a bug in the earlier versions which would cause this
meaningless 6 of 711 type of problem. You should get at least 100 hits
if the total is this high.

Frankly, this is a bit complicated. The magic happens in
LuceneCommon.cs and LuceneQueryingDriver.cs - which gets all the
matches back in terms of document ids, and then has extract the
relevant fields for all the documents to sort and top-100 them
correctly. Sorting by most recent is the current strategy but it
should not be hard to extend it.

See above.
