Re: Specify metadata per word/term in a string

[joergpra...@gmail.com]

There is a related feature that is called payloads for terms. In
Elasticsearch you can assign payload to terms, e.g. numbers for custom
scoring.

See also

https://github.com/elasticsearch/elasticsearch/issues/3772
https://github.com/elasticsearch/elasticsearch/pull/4161

It uses DelimitedPayloadTokenFilter

hi, thanks for the answer.
But that would stop me from enabling highlighting for such queries. Can you 
think of any workaround for highlighting also to work?

Re: Specify metadata per word/term in a string

Hello Neeraj ,

First of all you cant return a "hello" from Elasticsearch.
Elasticsearch works on feed level basis.
Which means if you want to search hello , you will get the feed with the
text "hello elasticsearch search world" but not just hello.

Only way I can think of create a different document for each word. So a
document would look like -

{
 "word" : "hello",
"code" : 25
}

here , you can get it worked.

If you want to retrieve the text also , give it as follows -

{
  "text" : "hello from Elasticsearch" ,
 "words" : [
{ "word" : "hello" , "count" : 25 } ,
{ "word" : "from" , "count" : 22}
   ]
}

WHERE words field is nested type.

Thanks
Vineeth

Specify metadata per word/term in a string

[Neeraj Makam]

Hi

Given a text,say "hello elastic search world",
is there a way i can associate a field or some metadata per word in the 
text on which i can later query? 
for eg: give code number to each word, and should be able to search like
text = "hello" AND code = "25"
i.e return all "hello" words which have 25 in their code metadata.
