I've been wondering about the tag synonyms system - the mechanism seems quite robust, but I'm missing the ability to define a relation between tag A and a combination of tags B+C. A sort of one-to-many / many-to-one synonym mapping. Couldn't find this discussed anywhere here.

For example, we have the tag, which is often useful but not extremely common, and then there are also his older brothers and . Either of them alone is not the same thing of course, but shouldn't questions marked with the combination of both pop out when we search for the ?

And on the other hand - shouldn't questions marked as get displayed when searching for either or alone? Or perhaps only when doing a combined search somehow?

This could be pretty useful, especially given the limit on tags. Would love to hear your opinions, maybe it's just over-engineering this.

Any hierarchical requests for the tag system have always been turned down in extremis.

What you have to do is either search for all 3 tags, the default is AND searching:

[graph] [algorithm] [graph-algorithm]

or you can OR search:

[graph] OR [algorithm] OR [graph-algorithm]

That's really a pain. The amount you need to search for is O(n!) when it should be just O(n) – Cole Johnson Nov 19 '13 at 4:40
I'm using AND/OR searches, but this doesn't help against unknown combinations, not to mention it explodes the length of the search string. I wonder why there's such an objection. – Leeor Nov 19 '13 at 4:44
