Add new search type - Commit Hash / Commit Hash Starts With

I like to search commits based on commit hash.
When we release software we number it like 
<Major Version>.<Minor Version>.<Patch Version>.<Commit Hash>

So when there are problems reported, I go search for Commit where error was spotted.

So if support for searching by commit hash has would be welcomed. 

Also if you can add option to search like, that you start to look for first character in hash number. 
Because under <Commit Hash> we show only first 8 numbers of hash not whole hash number.

For example if commit is:
d1116676626acca1edfb3611c35e517d3ba1a535 [d111667] 

So when I write in search bar  D111
It would me return all commits which start with D111 and not commits which contain D111 inside of commit hash number.

Or you could add multiple search types or option to chose which Hash search mode would be selected.
