Answer 1

Obviously my attempt to store a query in mongo the way I did was foolish as became clear from the answers from both @bigdatakid and @lix. So what I finally did was this: I altered the naming of the fields to comply to the mongo requirements.

E.g. instead of $or I used _$or etc. and instead of using a . inside the name I used a #. Both of which I am replacing in my Java code.

This way I can still easily try and test the queries outside of my program. In my Java program I just change the names and use the query. Using just 2 lines of code. It simply works now. Thanks guys for the suggestions you made.

String documentAsString = query.toJson().replaceAll("_\\$", "\\$").replaceAll("#", ".");
    Object q = JSON.parse(documentAsString);
