I'm using ES 0.90.7. Is there a way to do \_id mapped to a custom value which is based on more than one field? > Like i want \_id to combine srId and closeDt as our document key? this one doesnt work. { "mappings": { "json": { "\_id": { "path": "srId.closeDt", "properties": { "srId": { "index": "not\_analyzed", "type": "string" }, "closeDt": { "index": "not\_analyzed", "type": "long" } } } } } }' ---

You should do that on a client level and add a new attribute in your doc or send the right \_id.

Hi David, I'm using fsriver plugin. Is there a way to specify a script to generate a field like how couchDB river plugin is able to do. > { "couchdoc" : { "\_id" : { "path" : "doc\_rev\_id" } } } { "type" : "couchdb", "couchdb" : { "script" : "ctx.doc.doc\_rev\_id = ctx.doc._id + '_' + ctx.doc.\_rev" } } ---

No. Scripts are not supported in fsriver. What do you want to add with scripts? -- David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 16 janv. 2014 à 23:56, vinamar [vinamar@gmail.com](mailto:vinamar@gmail.com) a écrit : > Hi David, > > I'm using fsriver plugin.
