Hello all,

As mentioned previously, the current version of the Android app contains an A/B test where it presents "read more" suggestions to the user, based on (a) the standard "morelike" query, or (b) the new "opening_text" query.

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%:

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.
