Elasticsearch how to return the number of maching term for each document
For checking a single document, you can retrieve this kind of information using the explain API : http://www.elasticsearch.org/guide/reference/api/explain/
If you need this information collected along with the query results, you can just add the "explain": true to the body sent to the _search. Ex :
{ "explain": true, "query": { "term": { "description": "test" } }}With this parameter, you will get for each hit the associated _explanation data. Ex :
"_explanation": { "value": 1.4845161, "description": "fieldWeight(description:test in 63), product of:", "details": [ { "value": 1, "description": "tf(termFreq(description:test)=1)" }, { "value": 5.9380646, "description": "idf(docFreq=23, maxDocs=3348)" }, { "value": 0.25, "description": "fieldNorm(field=description, doc=63)" } ]}
