Free-form search query support

Code:

dc:title contains "A" or dc:title contains "B"

and like

Code:

dc:title contains "B" or dc:title contains "A"

the result set is not the same.

I am currently away from home and I will investigate this when I return home. It would be helpful if you could say which of these queries (if any) is producing a correct result and which is producing an incorrect result.

Quote:Also, for another search criteria, which are legitimate according to UPnP specs, we are getting "Unsupported or invalid search criteria" error, e.g.:

Code:

dc:title contains "A" and dc:title contains "B"

In forums, we found a post saying that free-form search queries are (or at least, were) not supported; what subset of search queries is currently supported in minimserver? What are the cases when a search query would be processed without an error, but yield invalid results?

As I understand it, there is no server that fully supports the free-form query syntax in the UPnP specification. My intention with MinimServer is to support the query forms that UPnP control points are sending. Which control point are you using to generate the queries that aren't supported?

If MinimServer accepts a query as supported, the results should never be incorrect. If this is happening, it is a bug and I will fix it.
