Using Elastic Search as a No-SQL for financial analytics with reasonable accuracy (exact terms match with non-analyzed strings, histogram aggregations)

Hello Elastic Search forum,

quick question regarding accuracy of results, since ES is a search engine.
Can one use ES for financial reporting where accuracy is important. E.g.
using exact terms matching (non-analyzed query strings) and histogram
aggregations? Basically using it as a No-SQL database for analytics (not
for text search).

The fact that counts from different shards are an approximation has me a
bit worried that this strategy might not work out. Been reading up on
accuracy and might be able to wing it with accepting error rates on certain
reports for the trade-off of speed.

Regards, Chris
