Annotatable entities should all be findable in the same search box

[suzialeksander]

On the main landing page, there is a search box for "Filter by Gene Product", and one for "Filter by Term". SGD needs to use both to find entities we've annotated- proteins/genes in the GP and complexes in the second, which isn't intuitive and is easy to forget if you don't look for complexes often.

These should be findable in the same search box, is there any way to add the complexes to the GP search box? Or have one general search box that will return hits in any field?
