I see that Elasticsearch version 0.90.0 is used in Mayocat. This version is rather old. Also, what I understand is that full-text search feature is not available.
Existing search features based on Elasticsearch are in class MarketplaceResource and are based on metadata and is NOT a full-text search.
Upgrading to higher version of Elasticsearch breaks compilation of Java source code.
Request you to comment on the observations above and the roadmap for additional search features.
Thanks and Regards,
