I have converted a pdf file into json by using tika and json library in python. While i want to search for a keyword in my index, I also want to have the page no. of the pdf file from which i extracted the data to index into elasticsearch. Is it possible? If yes, then please tell what should be my approach.  
TIA.

Please update the title of your post to something more meaningful.

Yes. But only if you know it. So it depends on how the documents you are sending to elasticsearch are looking like.  
I mean that AFAIK with Tika, you don't get that back.

For example if you send something like:

```auto
PUT book/_doc/foo
{
  "text": "bar .... bla bla ... baz"
}

```

Then there is no page number and you can't do anything about it.

But if you send

```auto
PUT page/_doc/foo_1
{
  "page": 1,
  "text": "bar"
}
PUT page/_doc/foo_2
{
  "page": 2,
  "text": "bla bla"
}
PUT page/_doc/foo_3
{
  "page": 3,
  "text": "baz"
}

```

Then it's obvious. So all the hard work has to be done on the extraction side, not on elasticsearch side.
