Track search phrases when using unified search?

Hi,

Is it possible to track search phrases (most common/without hits) when using unified search? If so, can anyone provide some dummy code on how to achieve this?

Note that I don't want to track clicks or anything, just the search phrases. I tried enabling click tracking but ended up with this ugly URL which I don't want to expose to the end user.

We're using EPiServer CMS 10.10.4.0 along with EPiServer Find 12.6.2.0.

Thanks!
