I wonder, how do I produce a query string that will allow me to search for both a track title plus an artist name or an album title?
I am trying to figure out how I in the easiest way possible can get to a specific version of a song, when it has been recorded by many different artists.
And example could be “Little Wing” recordings - let us say I know I just want to go as direct as possible to the one by “Sting”, on his “Nothing Like the Sun” album.
So, I could start out by searching for “little wing”, which gives me a list of “Little Wing” recordings. In some cases I am lucky enough that the version I am looking for is listed on the few matches that Plex chooses to display. I think ~10 on the IOS platform.
But, usually I am not that lucky, and the next thing that comes to me to do is typically to search for for example “little wing sting”, or “little wing sun” (if I am lucky enought to be able to remember the album name) … but, both returns with the message: “No Results - Try a different query”.
What is the trick that I miss? 
The library that I am searching is a Premium Music Library.
