The Search Engine is able to:
Index about 40,000,000 messages per day with continuous searching by the index.
Process 8,000 analytical queries every minute
Be easily scaled
The Highlighting Objects Service:
Is optimized for operating speed and RAM consumption.
Is able to work with about 5,000 object flows with 2,000,000 messages per day.
Consumes from 2 to 4 GB RAM.
Loads about 30-80 percent CPU.
"~" distance both way, for example (one ~3 two)

Quick start ShardDocumentIndex - you can use it if your index is too large
Quick start HighlightObjectService. The service can highlight objects in the text
Quick start TextCompareService. Compares two strings
