Background:

Based on the results from T149806 (see: T156300), this second A/B test for displaying sister project search results in a sidebar will have just one test group (displaying the project results based on recall) and one control group. Since the test results showed that we didn't get enough clickthroughs - mostly based on two bugs (T158935 and T158937) and the fact that the zero results rate for the queries entered on the original 4 wikis was higher than average - we decided to add in 4 additional wikipedias to be tested in this round.

This new test (T160004) is expected to last at least a week and will be run on the following wikipedias:

• Persian (tested in T149806)
• Italian (tested in T149806)
• Catalan (tested in T149806)
• Polish (tested in T149806)
• Arabic
• French
• German
• Russian

This ticket is to analyze the results of this second test, based on:

• if the user clicked on an individual result and what wiki project that result came from
• what position in the list was the selected result
• if the user clicked on the 'more from' on any wiki project result that was displayed
• important to compare control group that has sister wiki results vs test group that also has sister wiki results
