Support for "contains" find/search expression filter #189

Closed kowalcj0 closed 1 year ago

kowalcj0 commented 2 years ago

Hi,

Got a QQ: Does python-mpd2 support "contains" find/search expression filter? If if does, then it would be great to have an example of it somewhere in the docs or tests.

PS. The reason I asked about it, is because the "contains" filter can come it handy when looking for a track with partial track details.

Here's an example of how it works in mpc (I've compared an exact match query with a query that uses "contains" filter):

Given there's a track called "Chico Science & Nação Zumbi - Maracatu Atômico" in MPD DB
When client executes mpc with an exact match search: mpc search '((artist == "Chico Science") AND (title == "Maracatu Atômico"))'
Then the search returns no results
Given there's a track called "Chico Science & Nação Zumbi - Maracatu Atômico" in MPD DB
When client executes mpc with a contains filter search: mpc search '((artist contains "Chico Science") AND (title contains "Maracatu Atômico"))'
Then the search returns 1 matching track: "Chico Science & Nação Zumbi - Maracatu Atômico"

Thanks

Seems to work:

>>> c.find('(artist == "Eminem")')
