Hi, I am reading ES documentation. Trying to understand the finding\_multiple\_exact\_values at: [http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/\_finding\_multiple\_exact\_values.html](http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_finding_multiple_exact_values.html) I didnt understand what "open\_source" stands for at: { "tags" : ["search"] } { "tags" : ["search", "open\_source"] } [http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/\_finding\_multiple\_exact\_values.html#CO44-1](http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_finding_multiple_exact_values.html#CO44-1) I understand that's a token type or?? maybe I am missing something basic for my understanding. Anyone could fill that gap for me? Thanks, ray. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

"open\_source" is just an example value in the tags array. The example has two documents, both with just a single field called tags. The first one has one value "search" and the second one has two values (both in the same field, therefore it is an array) "search" and "open\_source" Document 1 { "tags" : ["search"] } Document 2 { "tags" : ["search", "open\_source"] } Multiple values in the same field can be thought of as an array, but Lucene underneath considers them to be two terms in the inverted index, both pointing at the same document.
