Question (issue) about NOT_EQUAL operator

[antonshpylenia]

Hello! I'd like to query articles by tags, and it works perfectly with EQUAL operator. However, if tags field contains more than one taxonomy tag, NOT_EQUAL operator doesn't filter results properly.

e.g.

I also tried NOT_IN operator, but you have to be precise in selection, so some articles could contain different amount of tags.

Thank you in advance!
