Release Group Search results as "Nagios Check Release"

This has to be some kind of joke because of the subject band but…
when running some tests i found an interesting response for the following query

http://musicbrainz.org/ws/2/release-group/?query=artist:"Staind"%20AND%20release:"1996-2006%20-%20The%20Singles"&dismax=true&fmt=json

That response being some kind of “Nagios Check Release”??
Did i find an easter egg at a bad bands expense?

This is a test release, assigned to the “MusicBrainz Test Artist”

I am not sure why this query is finding our test artist instead.

http://musicbrainz.org/ws/2/release-group/?query=artist:"Staind"%20AND%20release:"The%20Singles:%201996-2006"&fmt=json seems to work, but that involves switching the title around since we have it in the opposite order. Adding dismax back shows a ton of stuff that seems mostly useless.

Edit: http://musicbrainz.org/ws/2/release-group/?query="1996-2006%20-%20The%20Singles"%20AND%20artist:"Staind"&dismax=true&fmt=json seems more useful

The same query used in the OP gives 0 results in MB itself:
https://musicbrainz.org/search?query=artist%3A"Staind"+AND+release%3A"1996-2006+-+The+Singles"&type=release_group&limit=25&method=advanced

I guess dismax gives the search a bit more leniency, but I can’t really tell how it would end up with that release…

@reosarevok Is there a particular format to follow when constructing urls for Search/Browse/Lookup?

I mean, if rearranging a query would help results, how would one know say when searching the release-group resource, that one should not use the release parameter but instead issue the release as the query parameter… ect…

frankly ive found dismax to give way better search results as a whole, so much that ive adopted it as the default way to go…
From what I understand using SOLR is the closest way to get what comes up on a web search, but as in this case isnt quite that good.
