 Traditionally you design documents based on your data, store them into an index, and then define queries via the search API
 in order to retrieve these documents. The percolator works in the opposite direction. First you store queries into an

 This status page is a start, but we can do a better job of explicitly documenting the processes at work in Elasticsearch, and what happens in the case of each type of failure. The plan is to have a test case that validates each behavior under simulated conditions. Every test will document the expected results, the associated test code and an explicit PASS or FAIL status for each simulated case.
