The database field log_user_text of the table logging is unused by the api.
The api makes a join with the user table. Looks like old code, because
log_user_text was added in 1.16, maybe update for better performance?
The updater has a populate script for log_user_text.
Looking at the tables running on WMF, old revisions don't have log_user_text, but newer revisions do.
Doing this would require the action of back populating the logging table (populateLogUserText.php)...
It also might require the populateLogSearch.php script running...
Needs a little more research before we can take this one any further
I could almost do this, and then makes the next big deployment blocked on the script being run :P

It *should* JOIN or do a batch lookup, see bug 31863.
