- Want to have Compass distributed.
- Kimchy started working on a distributed Compass, by integrating with data grid solutions like GigaSpaces, Coherence and Terracotta. At its core, a distributed Lucene solution needs to be sharded.
- Also, with the advancement of HTTP and JSON as ubiquitous APIs, it means that a solution that many different systems with different languages can easily be used.
- It has a very advance distributed model, speaks natively JSON, and exposes many advance search features, all seamlessly expressed through JSON DSL.
- Solr is also a solution for exposing an indexing/search server over HTTP, but I would argue that ElasticSearch provides a much superior distributed model and ease of use.
