== Multi termvectors API

Multi termvectors API allows to get multiple termvectors based on an index, type and id. The response includes a `docs`
array with all the fetched termvectors, each element having the structure
provided by the <<search-termvectors,termvectors>>
API. Here is an example:

[source,js]
--------------------------------------------------
curl 'localhost:9200/_mtermvectors' -d '{
{
   "docs": [
      {
         "_index": "testidx",
         "_type": "test",
         "_id": "2",
         "term_statistics": true
      },
      {
         "_index": "testidx",
         "_type": "test",
         "_id": "1",
         "fields": [
            "text"
         ]
      }
   ]
}'
--------------------------------------------------

See the <<search-termvectors,termvectors>> API for a description of possible parameters.

The `_mtermvectors` endpoint can also be used against an index (in which case it
is not required in the body):

[source,js]
--------------------------------------------------
curl 'localhost:9200/testidx/_mtermvectors' -d '{
   "docs": [
      {
         "_type": "test",
         "_id": "2",
         "fields": [
            "text"
         ],
         "term_statistics": true
      },
      {
         "_type": "test",
         "_id": "1"
      }
   ]
}'
--------------------------------------------------

And type:

[source,js]
--------------------------------------------------
curl 'localhost:9200/testidx/test/_mtermvectors' -d '{
   "docs": [
      {
         "_id": "2",
         "fields": [
            "text"
         ],
         "term_statistics": true
      },
      {
         "_id": "1"
      }
   ]
}'
--------------------------------------------------

If all requested documents are on same index and have same type and also the parameters are the same, the request can be simplified:

[source,js]
--------------------------------------------------
curl 'localhost:9200/testidx/test/_mtermvectors' -d '{
    "ids" : ["1", "2"],
    "parameters": {
    	"fields": [
         	"text"
      	],
      	"term_statistics": true,
      	…
    }
}'
--------------------------------------------------

Parameters can aslo be set by passing them as uri parameters (see <<search-termvectors,termvectors>>). uri parameters are the default parameters and are overwritten by any parameter setting defined in the body.
