Limit search results

[Phrogz]

I have a DB that's currently at 17k songs (and growing). Some search terms can produce a lot of results, like:

@mpd.where file:'.'
@mpd.where any:'e'

Calls like this take 1.3 seconds on the server before they return. In my interface I then go on to truncate the results to the first 500. I'd like to be able to:

@mpd.where {file:'.'}, {limit:500}

and have the results limited for me.

I realize that this requires MPD support. I've posted a feature request on the MPD forum.

(FWIW, I also tried modifying build_songs_list in parser.rb to accept an optional limit, to reduce the number of songs created in the map. Reducing the map set from 16883 songs to 500 songs only reduced the time from 1.27s to 1.23s, a negligible savings.)

Apparently this is possible already in MPD:

You can use the "window" argument to limit the search. That's a 0.20~git feature.

The library is currently a bit behind, we're currently supporting all features up to 0.18 (#16), I think. We'd have to go and pull out any protocol changes listed for 0.19 and 0.20 http://git.musicpd.org/cgit/master/mpd.git/plain/NEWS
