It will be difficult for me to support free-form queries entered by the user.

foo_upnp queries are not free form. They follow this pattern (had to check the code because I didn't remember at all):

upnp:class derivedfrom "object.item.audioItem" and ( [<upnp tag> <op> "<query string>"]+ )

where

<upnp tag> := dc:title | upnp:genre | upnp:album | upnp:artist | dc:creator | dc:publisher | dc:description | upnp:userAnnotation | upnp:longDescription

<op> := = | contains

Example of request entered in the UPnp browser search field mapped to UPnP search query


artist HAS foo => upnp:class derivedfrom "object.item.audioItem" and (upnp:artist contains "foo" or dc:creator contains "foo")


album IS foo => upnp:class derivedfrom "object.item.audioItem" and (upnp:album = "foo")


entering just a search term will search all upnp tags above that the server claim to support with GetSearchCapabilities:

foo => upnp:class derivedfrom "object.item.audioItem" and ( dc:title contains "foo" or .... or upnp:longDescription contains "foo")
