_*Once comprehensive index processing capabilities is added to ORC i.e, Hadoop, it can be used to build indexes to other types of files in Hadoop.*_

Some candidate index types are given below
* Binary-Tree
* B-Tree
* B+-Tree
* Bit-Map
* Search Indexes

Search engines such as Solr, Elastic-Search etc. can use these index processing capabilities.
