We just released new versions of the wikimedia-extra plugin, a grab bag of useful extesions that we use at the Wikimedia Foundation. The new versions are: 1.3.1 for Elasticsearch 1.3, 1.4.1 for Elasticsearch 1.4, and 1.5.0 for Elasticsearch 1.5.
- id_hash_mod filter that is useful for independent processes to get non-overlapping portions of another data set. We use it for reindexing across multiple processes without any inter process communication.
- super_detect_noop native update script that updates the source document using a declarative list of tolerances and behaviors. It supports things like treating lists as sets and skipping updates for numbers when the new number is "close enough" to the value in the source. We use it on update instead of a groovy script.
- field_value_factor_with_default is just a backport of support for the missing parameter for ``field_value_factor```.
- Elasticsearch 1.5 support.
