# Index backend for Gerrit, based on ElasticSearch

Indexing backend libModule for [Gerrit Code Review](https://gerritcodereview.com)

component from v3.5.0-rc3 as part of [Change-Id: Ib7b5167ce](https://gerrit-review.googlesource.com/c/gerrit/+/323676).

Note that, ElasticSearch source code is no longer Apache 2.0-licensed for versions
7.11 and newer. See ElasticSearch [2021 license change](https://www.elastic.co/pricing/faq/licensing)
for more information.
