Using java driver to post documents in mongodb, performing a find() function on the console, some field-names appear repeated several times, all with the same values, when updating it: they behave like one.
When dumping it, and reading output from bsondump, the field is equally repeated several times, with same values...
There's nothing in particular with the field name, other than having a * (asterisc) in the middle (in order to substitute the DOT), like other fieldnames which doesnt appear repeated.
The field is located at an embeded doc, its path is: domainCounters.site*com.counts (integer)

The problem here, is the fear of erroneously growing documents, unexpectedly without pattern, with no solution to the 4Mb doc. limit
