Hi You carnt search for H1 in the advanced search bar because you are limited to 3 words or higher so for example if you had H11 then searching for H11 will work. Searching for H1 won't work as it is two words.

Your word minimum is three words or higher.

So... can it be changed? A search for a title with h1 is totally legitimate. I was sure I reported that bug and couldn't find it for maybe ten minutes using Phab's search, and then I found it using Google site search in ten seconds. If it's good for Google, why wouldn't it good for Phabricator?

Yep it can with a simple change to a mysql innodb config and then a reindex.

I've submitted a patch here https://gerrit.wikimedia.org/r/#/c/315057/ that currently has -1.

Doint forget google has a very advanced search bar so it will be very much more better then phabricator's.
