Exception to search engine rules for "SN" request

[Longman]

When I try to search "SN" in search bar, I get this message:

The search could not be completed because the search keywords were too short, too long, or too common.

Would be great to make an exception for "SN" request, because this abbreviation is used more often than "sodium nitrite" itself.

Same thing I thought

It's a feature of xenforo that you can't search keywords that are too short. I very much doubt this can be manually changed, but I agree it would be nice to have shorter minimum length keywords.
