ouch, that is not at all the result we were hoping for. Just goes to show why we have to test these things and not just take a few examples that perform badly in one set and look to do a better job with some different options. Thanks for putting this together!

Here are the results from the last ~10 days of the test[0]: - The clickthrough rate using the default morelike query is (and has been) around 15%. - With the new opening_text query, the clickthrough rate decreases to about 12%: Inline image 1 Therefore, it seems that the new query has a nontrivial negative effect on CTR :( We'll plan on removing this test in the next release of the app, but we'll be happy to plug in a different or updated query, if it will be of further use to Discovery.
