ElasticSearch Essentials - Additional functionality for forums running XenForo Enhanced Search (ElasticSearch).
This add-on REQUIRES XenForo Enhanced Search and ElasticSearch to be installed. Without it, this will not do anything.
When your users type in the search bar on your forum they will see suggestions based on what they have typed so far. The terms come from phrases used in your index rather than just common words. This means that it should work well for niche boards, any language, etc... This can really help reduce missed searches....
Thanks to @MattW for helping set up ElasticSearch on my server along with beta testing. Thanks to @Kevin and @empire for testing and giving valuable feedback.
