⚠️ IMPORTANT Right now this is an early stage work, the query builder logic does not scale and needs performance improvement

Fixes #2633
Fixes #1197

This PR adds a new field in the filters modal to filter entries by tags.

The available operators are:

• Match a given tag (exact match), e.g. software (referred to inclusion condition below)
• Not match a given tag by prepending the minus sign to the tag name (exact match), e.g. -software (referred to exclusion condition below)
• Limited pattern matching using '%', for example topic:% would match entries having either topic:software or topic:hardware, whereas -science:%' would exclude entries having either science:healthorscience:space`

You can add several conditions by using a comma, for example: software,-hardware.

The final expression can be summarized as: "(match ANY inclusion condition) AND (do not match ALL exclusion conditions)"
This means that the expression software,hardware would return all articles having either the software or the hardware tag.
