If grouping is not possible, offer an easy way to show hits instead

[jan-niestadt]

Right now, if I group on a span attribute (say, <named-entity type="..."/>) and then change my query and search again, it will try to group again. But if my results no longer includes named entities, this grouping is impossible. An error is shown, but there is no easy way to just show the hits for the query I entered. I have to copy the query, reset, paste the query, and press search again. It would be helpful to make this easier for users.

Examples:

This query groups on span-attribute <u ana="..."/>.

If I now change the Expert query to just "de" and click Search again, I get an error message because it assumes I want to perform the same grouping again, but that's not possible with this query. Getting out of this situation and back to searching is a bit annoying for me and confusing for regular users.
