Hi Fernando,
thank you for the feedback. Linking GeoTools DEV mailing list since
this actually turns out to be related whit GeoTools MongoDB store core.
So if I understood correctly, $or clause is correctly supported since
MongoDB 2.6? which was released 5 years ago [1]?
GeoSolutions is using MogoDB driver:
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>3.3.0</version> <type>jar</type>
<optional>false</optional>
</dependency>
... 3.3.0 is only compatible with MongoDB 2.6 and more recent versions
[2].
So +1 one for your suggestion Fernando:
* activate $or support in GeoTools MongoDB store
* add a Java property environment property that would allow the deactivation
of the $or operator support, to be on the safe side
Best regards,
