This should be done after 1-2 days of T149806 going live. Things to check for:
- Group sizes are similar across wikis (e.g. we don't want to see that 80% of the users are in control group on Italian Wikibooks vs 20% on Polish Wikisource)
- Events are of type: 'click' (click on one of the normal results), 'iwclick' (click on a textcat-powered result from another language), or 'ssclick' (click on one of the sister projects displayed in the sidebar)
- extraParams field should contain URL of the clicked result (including "More from" links -- see note below for those) and the position of the box (wiki) in the sidebar. Note:
For a click through to an article this would be, for example:/wiki/s:History_of_Iowa_From_the_Earliest_Times_to_the_Beginning_of_the_Twentieth_Century/3/Counties/Clayton
That would indicate they clicked an individual results, and that result was for wikisource.
- Merging TSS2 data with CirrusSearchRequestSet data to get list of wikis that yielded results and how many
- "More from" links:
For a click through to the 'more from' button this would be:https://en.wikibooks.org/wiki/Special:Search?search=guttenburg&fulltext=1
It looks like that will consistently be 'Special:Search' regardless of the wiki it's run on, but we should re-validate that after deployment. The 'ssclick' events for these will have the same position argument, indicating the position of the selected wiki in the ordering of the results.
