Based on the finalized design from T146663 and T139310, this A/B test will have a test group that will be shown thumbnails for the top 3 search query results and updated metadata for each search result. A control group will see the currently existing search results page.
> This test is expected to last a week - the Wikipedia where this test will be run on is yet to be determined, but will be based on community input.
**Test group users will see for the //top 3// search results returned**:
* thumbnail (as available) image for the search result
**Test group users will see for //all search results// returned**:
* word count
* number of revisions
* last updated date
** this could be shown as //Month Day, Year// or //2 years, 4 months and 3 days ago//
**Bucket testing** logic //generally// is as follows:
- 1 in 200 users are included in EventLogging
- Of those 1 in 200 users, 1 in 10 are included in the test
- Of those 1 in 10 users
-- 50% go in a **test** group, labeled "serp_add_thumbnails"
-- the other 50% of users will go in a **control** group, labeled "serp_no_thumbnails"
- The remaining chunk of the original bucketed 200 users will get a NULL (the string null, or the MySQL null, we can detect either).
**Eventlogging** needs to capture:
* if the user clicked on any of the top 3 results
* what position the result was in that the user clicked on (1st, 2nd or 3rd search result)
