Author: {'name': 'Chi-I Huang', 'email': 'chii.huang@mongodb.com', 'username': 'chiihuang'}Message: Always falls back on FilterNode, given that any FilterNode with fields indexed is supposed to be converted to a SargableNode during the substitution phase. Adds a query knob to control this behavior. |
