Limit number of article recommendations. The default is the number of articles configured for your placement. The limit you specify must be <= the number of articles configured for your placement.
Optional bucket number override; if you don't know what this is or haven't received instructions from Gravity to use this parameter, then it is safe to ignore.
If FALSE, you *must* log your impression using com.gravity.gdk.impression.Impression.log.
Article recommendations are generated against a placement. Placements at this time are configured for you by a Gravity Account Manager.
