10 alternatives to elasticsearch

elastic/elasticsearch — Free and Open Source, Distributed, RESTful Search Engine (78,386 stars, Elastic-2.0, search, analytics, testing).

These are the closest projects in the JustClaw-It index that we serve licence-cleared code from, ranked by relevance and by our code-quality score (1–10, the mean over each repo's graded components: completeness, code quality, deployability, reusability, strategic value). JustClaw-It does not serve code from elastic/elasticsearch itself (licence class: non-commercial), so these alternatives are the licence-cleared route.
