19% of queries giving "no results" seems really bad.

# *Percentage of queries that give 0 results: *19%

We've now got some preliminary data in about how effective our search is in mobile apps. Note that this is only half a day's data, and it's sampled at 1%. High-level metrics: - *Number of searching sessions which end by tapping on a result:* 91% - *Percentage of queries that give 0 results: *19% - *Mean queries per searching session:* 3.8 - *Median user-perceived time taken to retrieve search results: *486ms - *90th percentile of user-perceived time taken:* 898ms My quick take-homes from this: - 91% clickthrough seems pretty good. - 19% of queries giving "no results" seems really bad. - The combination of the above two means users are generally finding what they need, but that it's a struggle to do it. - User-perceived performance seems pretty good; 90% of our users get search results within a second! What I think our next steps are: - Push out our new search improvements and see how these baselines change. - Try to tackle the "0 results" problem, which seems to be more of a problem than clickthrough.
