The indexing is done by taking the indexable fragments from search, grabbing their XML via SearchIndexableResources, and then looking for controllers defined in preferences. For each controller found, we take the combination of the fragment providing the XML and the Preference info to create an indexable row. Buiding a Slice will be handled in a subsquent CL, but a prototype can be found here: ag/3324435 Test: robotests Bug: 67996923 Change-Id: I48668618079bcc3da55ab77b7323ee8e467073af
