Make feedback for the same search term cummulative

[osmers]

Motivation

With the planned changes for the feedback function in the app (adding a "did you mean" function), we might receive more feedback for the same search terms. It would be helpful to admins of the municipalities to see a count of how many times the term was searched for.

Proposed Solution

Accumulate feedback similarly to the up or down votes - maybe something like number of searches for this term in total. In the process we could also think about separating the two feedbacks (one for positive/negative feedback) and one for search terms that were not found.

Alternatives

Keep it as it is.

User Story

As an admin I want to see how many times a specific term was searched for so that I can prioritize which information to add first.
