An explorative approach to QBE trying find possibilities and limitations. We now support querying documents by providing a sample of the given object holding compare values. For the sake of partial matching we flatten out nested structures so we can create different queries for matching like:
{ _id : 1, nested : { value : "conflux" } }
{ _id : 1, nested.value : { "conflux" } }
This is useful when you want so search using a only partially filled nested document. String matching can be configured to wrap strings with $regex which creates { firstname : { $regex : "^foo", $options: "i" } } when using StringMatchMode.STARTING along with the ignoreCaseOption. DBRefs and geo structures such as Point or GeoJsonPoint is converted to their according structure.

We changed BasicQuery to consider its parent getFieldsObject() when not given an explicit fields DBObject.

Added method, field and annotation target to @Field annotation explicitly. Fixed copyright date ranges where needed.
Tweaked formatting in test cases.

We now distinguish between aggregation operations that replace fields in the aggregation pipeline and those which inherit fields from previous operations. InheritsFieldsAggregationOperation is a nested interface of FieldsExposingAggregationOperation is a marker to lookup fields along the aggregation context chain. Added unit and integration tests. Mention lookup operator in docs.

Refactored the query execution out of AbstractMongoQuery into MongoQueryExecution. Made sure the streaming execution lazily applies the projections, too.
Added a DtoInstantiatingConverter to be able to copy data from created entities into DTOs as we cannot hand the DTO type into the MongoTemplate execution in the first place as it's going to be used for the query mapping currently.
Some JavaDoc here and there. Moved converter factory registration into MongoConverters.getConvertersToRegister() for consistency with others.

We now convert AtomicInteger and AtomicLong to the required Number target type by calling get() followed by the actual conversion. This allows to directly use these types e.g. as part of an Update: new Update().set("intValue", new AtomicInteger(10));

The JavaDoc description references the EnableJpaRepositories annotation instead of the EnableMongoRepositories annotation.

MongoDB 3.2 RC1 decided to remove fields from statistics JSON documents returned in case no result was found for a geo near query. The avgDistance field is unfortunately missing as of that version.
Introduced a value object to encapsulate the mitigation behavior and make client code unaware of that.
A Query instance which might be part of a NearQuery definition is now passed through the QueryMapper to make sure complex types contained in it or even in more general types that have custom conversions registered are mapped correctly before the near command is actually executed.
@Indexed can now be used as meta-annotation so that user annotations can be annotated with it and the index creation facilities still pick up the configuration information.

We now also consider the limit set via MapReduceOptions when executing mapReduce operations via MongoTemplate.mapReduce(…).
MapReduceOptions.limit(…) supersedes a potential limit set via the Query itself. This change also allows to define a limit even when no explicit Query is used.

We now do a defensive check against the actual WObject of WriteConcern to avoid the IllegalStateException raised by the new java-driver in case _w is null or not an Integer. This allows us to run against recent 2.13, 2.14, 3.0, 3.1 and the latest 3.2.0.

We now use RepositoryMetdata.getIdType() to provide a fallback identifier type in case the entity information does not hold an id property which is perfectly valid for MongoDB.
Original pull request: #333.
Previously calling the method multiple times overrode the result of previous calls. We now use addMultiFieldOperation(…) to make sure already existing values are kept.
Polished JavaDoc and implementation as well as tests. Extracted Tuple to Spring Data Commons. Moved exception translation into MongoExceptionTranslator.
Changed implementation of DefaultBulkOperations to consider the WriteConcernResolver of the underlying MongoTemplate to avoid exposing the WriteConcern on execution.
