Two ways to measure overlap between your query tags and a game’s tags:
Default
Containment
score = overlap ÷ your query size
- “Did it match the tags I care about?”
- Extra tags on the game don’t hurt the score.

Overlap = 2 • Query size = 3 → 2/3 = 0.67
Alt
Jaccard
score = overlap ÷ union
- Overall “vibe similarity.”
- Unrelated extra tags reduce the score.

Overlap = 2 • Union = 5 → 2/5 = 0.40
Tip: If you’re filtering tightly with Require all query tags, Containment will often feel
more intuitive.
