I have resources that I need to index, they look like the below, I index this into index "managedobject" and type as "host" using ../ managedobject/host { "xmlns:base":"[http://ontologies.domain.com//base/2009/08/base](http://ontologies.domain.com//base/2009/08/base)", "xmlns:host":"[http://ontologies.domain.com//base/2009/08/host](http://ontologies.domain.com//base/2009/08/host)", "base:DisplayName":"Host-960a8b54ecb34475a3d9b508738cc1fa", "base:LastUpdated":1335366724956, "base:LastUpdatedDateTime":"2012-04-25T11:12:04.956-0400", "base:Model":"PowerEdge 1565", "base:Name":"[Host-960a8b54ecb34475a3d9b508738cc1fa.lss.domain.com](http://Host-960a8b54ecb34475a3d9b508738cc1fa.lss.domain.com)", "base:Identifier":"tag:@domain.com, 2011:host:Host::Host-960a8b54ecb34475a3d9b508738cc1fa", "base:Identifier":"Host-960a8b54ecb34475a3d9b508738cc1fa", "base:Identifier":"[Host-960a8b54ecb34475a3d9b508738cc1fa.lss.domain.com](http://Host-960a8b54ecb34475a3d9b508738cc1fa.lss.domain.com)", "base:Identifier":"10.226.214.73", "base:Status":"OK", "base:Vendor":"Dell Inc.", "base:discoveryStatus":"Success", "host:CPUSpeed":"0.29 Ghz", "host:CPUType":"Intel(R) Xeon(R) CPU E5410 @ 2.33GHz", "host:CreatedBy":"Discovery", "host:FQDN":"[Host-960a8b54ecb34475a3d9b508738cc1fa.lss.domain.com](http://Host-960a8b54ecb34475a3d9b508738cc1fa.lss.domain.com)", "host:MultipathVersion":"4.7", "host:NumberOfCPUs":"4 x 1.08 Ghz Intel(R) Xeon(R) CPU E5410 @ 2.33GHz", "host:OperatingSystemVersion":"4.7", "host:PhysicalMemorySize":"304798513", "host:ShortName":"Host-960a8b54ecb34475a3d9b508738cc1fa", "host:VersionSolutionEnabler":"7.7" } My question is, to get a best performance do I keep the document structure the same or make some change to this representation? ---

It depends on how you want to query this data later. ---

Also, the above is not legal JSON, as you cannot repeat key names. Elasticsearch will actually index the above just fine, but if you are retrieving this \_source docs from Elasticsearch, there is a good chance that any JSON module that you use will accept only the last value for a repeated key. ---

Will a search on any of these Identifer return the same document? If it does not then I will need to make changes to this document.

It will return exactly what you sent it. So if your receiving code can handle illegal JSON, then you'll be fine clint > On Jun 13, 3:27 pm, Clinton Gormley [cl...@traveljury.com](mailto:cl...@traveljury.com) wrote: > > > > "[base:Identifier":"tag:@domain.com](mailto:base:Identifier%22:%22tag:@domain.com), > > > 2011:host:Host::Host-960a8b54ecb34475a3d9b508738cc1fa", > > > "base:Identifier":"Host-960a8b54ecb34475a3d9b508738cc1fa", > > > "base:Identifier":"[Host-960a8b54ecb34475a3d9b508738cc1fa.lss.domain.com](http://Host-960a8b54ecb34475a3d9b508738cc1fa.lss.domain.com)", > > > My question is, to get a best performance do I keep the document > > > structure the same or make some change to this representation? > > > > Also, the above is not legal JSON, as you cannot repeat key names. > > Elasticsearch will actually index the above just fine, but if you are > > retrieving this \_source docs from Elasticsearch, there is a good chance > > that any JSON module that you use will accept only the last value for a > > repeated key. ---
