Thanks in advance.

Hi,
Indexing all fields in a record is possible in BDB but is fairly expensive since an index record will be written for every field. If you have a relatively small data set then perhaps this is not a problem, but be sure to do performance testing.
The common approach is to use a single secondary database (index) to create a many-many relationship. The key for this index will include the field name as well as the field value. This means that all fields can be indexed, including new fields that are added, using a single index and without changing code when new fields are stored.
Indexes are created using Environment.openSecondaryDatabase. In the SecondaryConfig that you pass to this method:
  - Call setSortedDuplicates(true) since more than one record can have the same key.
  - Call setMultiKeyCreator(...) since the index will contain multiple keys for a single record.
You implement the SecondaryMultiKeyCreator interface to extract the keys from your JSON record. This returns a set of keys, one for each field you want to index.
The format of the index key can be anything you'd like (as you know BDB uses byte arrays for keys). For example, you could use a string of the form NAME:VALUE as the key, so that you could do your lookups using that format. To serialize a string as bytes, use a class in com.sleepycat.bind.tuple such as StringBinding.
To do your lookups, pass your index key (NAME:VALUE) to SecondaryDatabase methods such as get().
See the javadoc for SecondaryDatabase, SecondaryConfig, SecondaryMultiKeyCreator. An example is in examples/je/ToManyExample.java.
Would something like that work for you?
