I'm trying to create an image metadata store, and obviously a single image can have 20 or more metadata fields. So if I enter this document into ElasticSearch, will it index/map all those fields? Such that I can query for every field? Or can I tell ElasticSearch what to index or not? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hello Albert , Few things here 1. Yes , you cal tell Elasticsearch which fileds to index and which field not to index. You can use index : " yes/no" property for each field in the schema to specify this. - [Specify which fields are indexed in ElasticSearch - Stack Overflow](http://stackoverflow.com/questions/13626617/specify-which-fields-are-indexed-in-elasticsearch) 2. There is a concept of \_all in Elasticsearch. This would be a super-set of all field values and to search on the entire document , you can simply search on \_all field. - [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-all-field.html#mapping-all-field) Thanks Vineeth On Sun, Aug 24, 2014 at 4:07 AM, Albert Lim [albertlim322@gmail.com](mailto:albertlim322@gmail.com) wrote: > I'm trying to create an image metadata store, and obviously a single image > can have 20 or more metadata fields. > > So if I enter this document into Elasticsearch, will it index/map all > those fields?
