Filtering on the date

[institut]

Hello,
I saw that the function "filter" allows to extract pieces of music then possibly to make a second extraction on the list obtained.
1 - what are the possible criteria for this filter? In doing tests I found "artist" and "album". These are the only ones?
2 - It does not seem that the "date" and "genre" are parts of the possible filters. However, it would be particularly useful to be able to extract by date using the operators AND OR <>
For example, I want to know the songs of "Johnny Hallyday", of the genre "Slow", Date>1980 AND Date<1990
Can we expect this essential function in Poweramp v3?

Thank you
