//createIndex ...

//Register Percolator

QueryBuilder qb = QueryBuilders.matchQuery("content", "taxes");  
client.prepareIndex(index, ".percolator", "harkinQuery")  
.setSource(jsonBuilder()  
.startObject()  
.field("query", qb) // Register the query  
.endObject())  
.setRefresh(true) // Needed when the query shall be available immediately  
.execute().actionGet();

//index with BulkProcessor  
for(i=0; i\< numDocs; i++)  
{  
JSONObject jDoc = getDoc[i];  
...

bulkProcessor.add(Requests.indexRequest(index).type(type).id(jDoc.  
getString("id")).source(jDoc.toString()));  
...  
}

Looking  
at [http://www.elasticsearch.org/guide/en/elasticsearch/client/java-api/current/percolate.html](http://www.elasticsearch.org/guide/en/elasticsearch/client/java-api/current/percolate.html),  
Percolate API is used like this, but I am not sure how I can use it in  
combination with bulk index request shown in my above code?

//Percolate  
PercolateResponse response = client.preparePercolate()  
.setIndices("myIndexName")  
.setDocumentType("myDocumentType")  
.setSource(docBuilder).execute().actionGet();  
//Iterate over the results  
for(PercolateResponse.Match match : response) {  
//Handle the result which is the name of  
//the query in the percolator  
}
