Using Meta allows to the define $comment, $maxScan, $maxTimeMS and $snapshot on query. When executed we add the meta information to the cursor in use.
We’ve introduced the @Meta annotation that allows to the define $comment, $maxScan, $maxTimeMS and $snapshot on a repository finder method.
Added tests to verify proper invocation of template methods
Use DBCursor.copy() for CursorPreparer.

Identifier initalization is now only triggered if field access is used. Before that the id initialization would've resolved the proxy eagerly as the getter access performed by the BeanWrapper would've been intercepted by the proxy and is indistinguishable from a normal method call. This would've rendered the entire use case to create proxies ad absurdum.
Added test case to check for non-initialization in the property access scenario.
We now initialize the ID property for proxies created for lazily initialized DBRefs. This will allow the lookup of ID properties for types that use field access without initializing the entire proxy.
Simplified implementation of ObjectPath to use a static root instance and hand the path further down until final resolution in MappingMongoConverter.readValue(…). This removes a bit of boxing and unboxing code both in ObjectPath and the converter.
Introduced ObjectPath.getPathItem(…) to internalize the iteration to find a potentially already resolved object.
Renamed parameters and fields of type ObjectPath to path consistently. Removed obsolete method in MappingMongoConverter.
Original pull request: #209.
Introduced ObjectPath that collects the target objects while converting a DBObject to a domain object. If we detect that a potentially nested DBRef points to an object that is already under construction we simply return a reference to that object in order to avoid StackOverFlowErrors.

Added support to execute full-text queries on repositories. Query methods now can have a parameter of type TextCriteria which will be triggering a text search clause for the property annotated with @TestScore.
Retrieving document score and sorting by score is only possible if the entity holds a property annotated with @TextScore. If present, any find execution will be enriched so that it asserts loading of the according { $meta : textScore } field. The sort object will only be mapped in case the existing sort property already exists - in that case we replace the existing expression for the property with its $meta representation.
This allows for example the following:
TextCriteria criteria = TextCriteria.forDefaultLanguage().matching("term");
repository.findAllBy(criteria, new Sort("score"));
repository.findAllBy(criteria, new PageRequest(0, 10, Direction.DESC, "score"));
repository.findByFooOrderByScoreDesc("foo", criteria);
For more details and examples see the "Full text search queries" section in the reference manual.
We now resolve the target type for CGLib-proxied objects and initialize lazy loaded ones before saving. As it turns out CustomConversions already knows how to deal with proxies correctly. Ee added an explicit test to assert that.

A simple call of toString() on a DBObject might result in an exception if the DBObject contains objects that are non-native MongoDB types (i.e. types that need to be converted prior to persistence).
We now use SerializationUtils.serializeToJsonSafely(…) to avoid exceptions.
Introduced ParameterBindingParser which exposes parameter references in query strings as ParameterBindings. This allows us to detect whether a parameter reference in a query string is already quoted avoiding wrongly double-quoting the parameter value.
Original pull request: #185.
Related ticket: DATAMONGO-420.
The fix for DATAMONGO-950 introduced a tiny glitch so that retrieving pages after the first one was broken in the repository query execution. We now correctly use the previously detected number of elements to detect whether the Pageable given is out of scope.

Let getValueInternal(…) use the provided SpELExpressionEvaluator instead of relying on the MongoDbPropertyValueProvider to create a new one. Removed the obsolete constructor in MongoDbPropertyValueProvider.
We now avoid creating a lazy-loading proxy if we detect that the property-value in the backing DbObject for a @Lazy(true) annotated field is null.
Original pull request: #207.
We replaced the constructor that accepted a Criteria with one that accepts a CriteriaDefinition to not force clients to extends Criteria.

We added some extract-methods to ProjectionOperationBuilder to be able to extract date / time components from projected fields.

SpringDataMongodbSerializer now defensively triggers mapping of the DBObject created by the default serializer. This asserts that ids buried in nested structures like { "_id" : { "$in" : ["x", "y"] } } are converted correctly.
Original pull request: #202.
We now use Spring Data Commons' @ReadOnlyProperty to meta-annotate @Score to mark it as read-only property.
Original pull request: #201.

SpringDataMongodbSerializer now overrides the necessary methods to create the appropriate DBRef objects when serializing data via Querydsl.
We currently disable the test case as it the fix taking effect requires Querydsl 3.4.1 which unfortunately breaks Java 6 compatibility. We include the fix nonetheless to allow users on Java 7 to potentially use the latest Querydsl.

Added build profile for MongoDB Java driver versions 2.12.3-SNAPSHOT and 3.0.0-SNAPSHOT. Added another property to be able to build manifests correctly as the snapshot versions aren't valid OSGi versions.
Adapted MongoExceptionTranslator to convert the new Exceptions being thrown for server timeouts and the deprecated values we currently handle.
We introduced @TextScore that can be used to mark a property to take { $meta : “textScore” }. In contrast to @Transient the value will be considered when reading documents.
The value can and will only get picked up if the score field is retrieved from the store.
Original pull request: #198.
Using TextQuery and TextCriteria allows creation of queries using $text $search.
{ $meta : “textScore” } can be included using TextQuery.includeScore. As the fieldname used for textScore must not be fixed to “score” one can use the overload taking the fieldname to override the default.
Original pull request: #198.
We now support creating text index based on information gathered on domain types.
Using @TextIndexed marks properties to be considered for the full text index. Use the weight attribute to influence document scoring during search operations.
Please note that using @TextIndexed on entity properties forces all properties of any sub document to be considered as part of the text index. Any set weight will in that case be propagated to the siblings taking the most recent weight information into account, which means that a the weight attribute can be overridden for properties in sub documents.
The setting the index default language can be done via @Document(language) while @Language can be used to define the language_override field.
As text search is disabled by default for mongodb 2.4 we use a jUnit ClassRule to restrict integration tests potentially creating text index (as the entities for testing are found in the classpath) to only be executed in when a 2.6+ mongodb server is present.
For usage hints please see section 6.3.4 (Text Indexes) of reference manual.

We now pass on type information for derived delete queries to the according delete operation. This propagates the information correctly to the according Before and After events.
Before this change the type would have been set to null in case of non collection like method return type.
Original pull request: #199.
We now check on intersections of given path and existing to not only check types and contained property names but also properties full path which must not be present in already traversed paths.
Additionally we’ll now catch any CyclicPropertyReferenceExceptions on the root level to prevent cycle detection interfering with application startup.
Original pull request: #197.
If a DBObject was handed into MongoTemplate.remove(…) we previously failed to look up the id value to create a by-id-query. This commit adds explicit handling of DBObjects by looking up their _id field to obtain the id value.
We now support referring to system variables like for instance $$ROOT or $$CURRENT from within aggregation framework pipeline projection and group expressions.
