How to do a highlight on percolation of existing document.

I have indexed a document. In this index,type and Id --\>\>  
POST [http://127.0.0.1:9200/sp/res/12](http://127.0.0.1:9200/sp/res/12)

Now i have to do percolation on this GET [http://127.0.0.1:9200/sp/res/12/\_percolate](http://127.0.0.1:9200/sp/res/12/_percolate)  
and i have to highlight the matches.

How can I do this for multipercolate also?

Please reply me with one example.

I found this link for percolating document. Bu this not for existing indexed document.

Please read [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21)

Especially the `Also be patient...` part.

You can read this: [https://www.elastic.co/guide/en/elasticsearch/reference/2.3/search-percolate.html#\_percolating\_an\_existing\_document](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/search-percolate.html#_percolating_an_existing_document)

Using Highlighting in the percolate api is the same as in the search api. Just refer to a field that is in the document you would like to percolate.

```auto
curl -XGET "http://localhost:9200/sp/res/12/_percolate" -d'
{
  "highlight": {
    "fields": {
      "your_field" : {}
    }
  }
}'

```

Thanks this works.

But for multipercolate how should I do? How can I highlight  
Below is my query:

POST [http://localhost:9200/sp/rs/\_mpercolate](http://localhost:9200/sp/rs/_mpercolate)  
{"percolate" : {"index" : "sp", "type" : "rs", "id" : "AVYnWUgDva7zbOd2yZQa" } }  
{}  
{"percolate" : {"index" : "sp", "type" : "rs", "id" : "AVYnWYK\_va7zbOd2yZQe" } }  
{}

In the mpercolate api each request consists out of two lines the head and body.  
The body is empty in your case and you should add highlighting there:

```auto
POST http://localhost:9200/sp/rs/_mpercolate
{"percolate" : {"index" : "sp", "type" : "rs", "id" : "AVYnWUgDva7zbOd2yZQa" } }
{"highlight" : { "fields" : { "your_field" : {} } } }
{"percolate" : {"index" : "sp", "type" : "rs", "id" : "AVYnWYK_va7zbOd2yZQe" } }
{"highlight" : { "fields" : { "your_field" : {} } } }

```

The request header and body must each be specified as a single line (the newline at the last line is required). Otherwise the mpercolate api fails.

From what programming language are you using ES? Maybe take a look at the official supported clients as they make integrating with the APIs easier.
