in a search field explicitly for hex encoded IDs it shouldn't be

In a generic web search that has to guess if my term was a hex encoded id ('cafe' is but almost certainly isn't intended as one..).. it's less obvious.

in the case of a clear hex encoded id of sufficient length, i would like to know there are zero exact results, but as long as it's still fast I would love some fuzzy matches after in case there was a typo in my term or in the indexed document.
