Advanced search fields need IDs

[allanaaa]

In the public interface, advanced search forms cannot be easily customized. Rather than build a whole structure around including or excluding each field with a checkbox, or dragging and dropping, site administrators could use CSS Editor to point to specific fields by ID and hide them.

Unfortunately, many fields do not have IDs:

Numeric Data Types is done well, but core and Mapping need some specificity. There may be other modules that add search fields - I can't think of any offhand.

I think the aria labels and classes should also be applied more consistently? @kimisgold maybe you can advise on the aria labels.

The original question (how best to offer customization on Advanced Search) can be discussed too, but this seems necessary either way.
