I'm not sure this data is meaningful. I recall searching for several real symptoms that I had, and the step 2 options were so far off that I decided to just try the suggested searches to see the sample results.

We observed that we had exact concept matches for over 2/3rds of the symptoms searched on the first try.

To get the rest we are doing two things: 1. adding common queries without matches into our symptom vocab 2. improving the suggested searches algorithm
