Specify metadata per word/term in a string
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. -- You received this message because you are subscribed to the Google Groups elasticsearch group.

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

Re: Specify metadata per word/term in a string
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 http://lucene.apache.org/core/4_7_0/analyzers-common/org/apache/lucene/analysis/payloads/DelimitedPayloadTokenFilter.html Jörg On Wed, Apr 30, 2014 at 1:06 PM, Neeraj Makam neeraj23...@gmail.com wrote: 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. -- You received this message because you are subscribed to the Google Groups elasticsearch group.
