The OR operator in the Search API doesn't work

[no-username2]

I'm trying to look for tracks by either ISRC ID, or by both track name and artist name, I try to do so in a single request using the OR operator in the search API endpoint but it doesn't really work.

When I search by ISRC ID alone it works

/search?type=track&q=isrc:USWB11101940

When I search by both track name and artist name it also works

/search?type=track&q=track:adventure artist:red hot chili peppers

But when I try to search by ISRC ID or by track name and artist name in the same query it doesn't really work, I mean when I provide a valid and existing ISRC ID AND a valid and existing track and artist names it works:

/search?type=track&q=isrc:USWB11101940 OR track:adventure artist:red hot chili peppers

But when I intentionally provide either a non-existing ISRC ID OR a none-existing track and artist names it doesn't fallback to the other side of the "OR" operator and it doesn't provide results even though it should.

Examples of the possible bug:

Valid and existing ISRC ID or none-existing track and artist names - no results (it fails on the track & artist names and it doesn't fallback to the ISRC ID)

/search?type=track&q=isrc:USWB11101940 OR track:adve1nture artist:r1ed h1ot chi1li pep1pe1rs

Non-existing ISRC ID or valid and existing track and artist names - no results (it fails on the ISRC ID and doesn't fallback to the track & artist names)

/search?type=track&q=isrc:11WB11101940 OR track:adventure artist:red hot chili peppers
