If you store the tags as a StringList wouldn't this query work.. WHERE tags = tag1 AND tags IN [tag2,tag3] AND tags != tag4
>From the docs it says the IN & != do run multiple queries behind the scenes so not sure if it will be as quick as running it in memory for a few hundred items, but if you need more than a few hundred items you are not going to be able to do it in memory before it starts timing out.
