If you want to use an external node, you must use a compatible version of Elasticsearch with your version of Smarter Search

...

As an example benchmark, Smarter Search for Bitbucket indexed the Linux code base which is approximately 15 million lines of code and half a million commits in 2-3 minutes with 6 GB of ram on non-SSD hard drives with an internal node. That said, it is recommended that for large codebases you use an external Elasticsearch node. For any concerns or questions, feel free to contact us.

External Node

For Bitbucket instances with large codebases and a lot of indexing, it's recommended to setup a separate Elasticsearch service. This will reduce the strain on Bitbucket for indexing, and should significantly improve performance. You can configure an external node in the settings page.

...

After installing the plugin in your bitbucket instance, you must enable indexing and trigger a reindex:

1. Go to Smarter Search for Bitbucket Global Settings page in the Bitbucket admin panel.

2. Enable Indexing by clicking the check box.

3. Click Save and Reindex to save the settings and subsequently reindex all repositories.

External Node (Elasticsearch 2.4.6)

...

Once the node is setup, you must configure Smarter Search for Bitbucket:

1. Go to Smarter Search for Bitbucket Global Settings page in the Bitbucket admin panel.

2. Enable Indexing by clicking the check box.

3. Uncheck the Internal ES Node checkbox.

4. Click Save and Reindex to save the settings and subsequently reindex all repositories.

Smarter Search for Bitbucket will then start indexing all of your bitbucket repositories in the background. It will take a few seconds to a few minutes to finish depending on the number and size of your repositories. For large Bitbucket instances, it is recommend indexing to be done during non peak hours.

By default, only the master and develop branches are indexed. Individual repo admins may modify these settings. See the Administration documentation page for instructions.
