Prevent full text search in Analytics features

Problem to solve

As noted in another issue, Analytics features do not support full-text search. However, they indicate they do because their filter bar says "Recent searches" and "Search or filter", and the "Recent searches" menu includes non-filter items:

Proposal

Either:

1. Enable full text search, or;
2. Prevent full text search (see screenshot below):
   1. Change "Recent searches" to "Recent filters"
   2. Change "Search or filter results..." to "Filter results..."
   3. Prevent non-filter values from being submitted (and prevent them from being stored as "Recent filters"?)
