I'm new to mongoDB, trying to formulate my query.
First in mongo.exe later converting to c++.
In the appended file you'll find the population of my testcase.
Next is the query "db.info.find({'colors.rgb.center.a0.i0.stdDev.1':{ $gt: 50, $lt:60 }},

)", which returns empty, whereas I expect the first entry.
The querey is more or less copied from the tutorial. Can you help?
