Search keywords containing a number seem to be completely ignored, or excluded from the search index. For example, if I search for "3D" or "h1" (with no other words) I get zero search results, even though I know multiple user suggestions exist with these exact terms in the title.

For some types of software, words containing digits are important terms that help users specify a particular feature. Search results are a mess when one of the main distinguishing words in the feature name is ignored.

I can sort of understand excluding terms that are 100% a number (though even then, I'm not sure of the benefit), but please don't exclude words that include a mix of both letters AND numbers/
