Elasticsearch is a distributed, RESTful search and analytics engine capable of solving a growing number of use cases. As the heart of the Elastic Stack, it centrally stores your data so you can discover the expected and uncover the unexpected.
searchengine search-engine full-text-search document-oriented percolator analytics nosql time-series aggregationLuwak is a high performance stored query engine. Simply put, it allows you to define a set of search queries and then monitor a stream of documents for any that might match these queries: a function also known as reverse search and document routing. This is similar to Elasticsearch Percolator.

Fluo makes it possible to update the results of a large-scale computation, index, or analytic as new data is discovered. When combining new data with existing data, Fluo offers reduced latency when compared to batch processing frameworks (e.g Spark, MapReduce).
