Log at DEBUG will show the MongoDB "query" filter. Should be clear from that if
all components of the JDOQL are in the datastore query.
An example
JDOQL : SELECT FROM org.jpox.samples.models.company.Person WHERE firstName ==
'Daffy' && personNum < 3
Fetching instances of collection Person fields={ "age" : 1 , "birthDate" : 1 ,
"emailAddress" : 1 , "firstName" : 1 , "globalNum" : 1 , "lastName" : 1 ,
"personNum" : 1} with filter={ "firstName" : "Daffy" , "personNum" : { "$lt" :
3}}
In this case the "filter" is complete, hence nothing to do in-memory. The
"fields" part of that line are the fields retrieved (i.e DFG)
