What does the json in the CURL request for this look like?

The dynamic creation of mappings for unmapped types can be completely  
disabled by setting _index.mapper.dynamic_ to false.

Thanks!

This is what I put into the elasticsearch.yml file when I start  
Elasticsearch for use in a non-ELK environment:

# Do not automatically create an index when a document is loaded, and do

# not automatically index unknown (unmapped) fields:

action.auto\_create\_index: false  
index.mapper.dynamic: false

And here's a complete example of a curl input document that I use to create  
an index with the desired types in which I don't want new indices, new  
types, or new fields to be automatically created:

{  
"settings" : {  
"index" : {  
"number\_of\_shards" : 1,  
"analysis" : {  
"char\_filter" : { },  
"filter" : {  
"english\_snowball\_filter" : {  
"type" : "snowball",  
"language" : "English"  
}  
},  
"analyzer" : {  
"english\_standard\_analyzer" : {  
"type" : "custom",  
"tokenizer" : "standard",  
"filter" : ["standard", "lowercase", "asciifolding"]  
},  
"english\_stemming\_analyzer" : {  
"type" : "custom",  
"tokenizer" : "standard",  
"filter" : [ "standard", "lowercase", "asciifolding",  
"english\_snowball\_filter" ]  
}  
}  
}  
}  
},  
"mappings" : {  
"_default_" : {  
"dynamic" : "strict"  
},  
"person" : {  
"\_all" : {  
"enabled" : false  
},  
"properties" : {  
"telno" : {  
"type" : "string",  
"analyzer" : "english\_standard\_analyzer"  
},  
"gn" : {  
"type" : "string",  
"analyzer" : "english\_standard\_analyzer"  
},  
"sn" : {  
"type" : "string",  
"analyzer" : "english\_stemming\_analyzer"  
},  
"o" : {  
"type" : "string",  
"analyzer" : "english\_stemming\_analyzer"  
}  
}  
}  
}  
}

By the way, I never mix indices that are used for more standard database  
queries with the indices used by the ELK stack. Those are two separate  
Elasticsearch clusters entirely; the former is locked down as shown above,  
while the latter is left in its default "free form" method of automatically  
creating indices and new fields on the fly, just as Splunk and ELK and  
other log analysis tools do.

I hope this helps.
