+Search engines luke can deal with
+====
+In no particular order:
+
+* [Apache Lucene](http://lucene.apache.org/). Most certainly luke can open lucene index produced by pure Lucene. Do people make pure Lucene these days?
+* [Apache Solr](http://lucene.apache.org/solr/). Solr and Lucene share the same code base, so it is natural that luke can open Lucene Index produced by Solr. 
+* [Elasticsearch](https://github.com/elastic/elasticsearch). Elasticsearch uses Lucene as its lowest-level search engine base. So luke can open its index too!

 Usually we don't do releases for minor version upgrades, because the major release usually can read the index of the next
 minor release.
