HSearch is a realtime search and analytics engine built on Hadoop. It excels in its ability to perform real-time search and analytics on both text content and database records. The scale and performance of HSearch is due to its unique indexing algorithm and parallel data processing across machines, keeping the overall cost of infrastructure to the minimum.

Some key features of HSearch are:

* Fast query on large datasets – queries typically return in milliseconds on terabytes of data
* Multiple data structures are used for storing the data depending on the nature of data
* LRU cache layer for frequently accessed data
* 5MB index cells to co-locate data by business entities and secondary rollup indexes for fast filtering on large datasets
