Method Summary

Modifier and Type	Method and Description
void	declareOutputFields(OutputFieldsDeclarer outputFieldsDeclarer)
void	prepare(Map map, TopologyContext topologyContext, OutputCollector outputCollector)
void	process(Tuple tuple) Tuple should have relevant fields (source, index, type) for storeMapper to extract ES document. If there exists non-empty percolate response, EsPercolateBolt will emit tuple with original source and Percolate.Match for each Percolate.Match in PercolateResponse.
