$lt and $lte queries using 'NaN' trigger invalid bounds asserts

    • Priority: Icon: Major - P3 Major - P3
    • 2.7.0
    • Affects Version/s: 2.6.0, 2.6.1-rc0

      db.nan.drop();
db.nan.ensureIndex({a:1});
db.nan.find({a: {$lte: NaN}});
      Show
      db.nan.drop(); db.nan.ensureIndex({a:1}); db.nan.find({a: {$lte: NaN}});

      Querying for '$lte: NaN' or '$lt: NaN' with an indexed field results in an invalid bounds assert. The assert is not triggered when querying against an unindexed field or when using $gt or $gte.

      Server output:
