We've added all the necessary code to experiment with defaultsort data and we now need to build some experimental indices before activating it on production wikis
We know of some possible drawbacks that could happen:
- bad suggestions when defaultsort is set to a non representative text
- hides too many suggestions
A test index should help to discover obvious problems, but replaying queries from search logs to detect if the result chosen is now hidden should really help to see any negative impact.
Recent checkin's (for reference):
Added DEFAULTSORT to search index field data
Added support for FLAG_SOURCE_DATA and defaultsort in completion suggester
