Highlight based on a field

Elastic Stack Elasticsearch
1

Hi ,

Following is a sample feed i have.

Feed - 1
{
"entity" : "YHOO",
"Content" : "Its a great day at yahoo (YHOO) today"
}

Feed - 2
{
"entity" : "GOOG",
"Content" : "Google(GOOG) is going to launch g+"
}

Now i want the highlighting output as

"Its a great day at yahoo (YHOO) today"
"Google(GOOG) is going to launch g+"

I want to highlight based on the field "entity" rather than a predefined
like YHOO where the latter will fail to give the output i am looking for.
Is this possible in elasticsearch ?

Thanks
Vineeth

If text that should be highlighted is stored with the record, wouldn't it
be faster and simpler to highlight text during indexing?

oops forgot to tell a important point.

Say i am tagging all the stuff i need to highlight while indexing , how am
i supposed to get the highlighted text while searching.
I will have to write a highlighter for myself by taking the entire source.
