Free-form search query support

[streamunlimited]

We are developing our own application, which communicates with MinimServer; thus, we would like to know what forms of queries can be safely used. I'm currently out of the office, but most remarkable problem I've seen is:

dc:title contains "Something" or dc:title contains "Else" returning a list of songs containing Something (I'm not sure about 'Else' now), but

dc:title contains "Else" or dc:title contains "Something" returning an empty search result.

We will try to generate a setup, in which this issue can be easily reproduced.
