Elasticsearch Couchdb river Mapping problem

Elastic Stack Elasticsearch
1

I have the Elastisearch couchdb river installed. I am looking to creating
mappings for my database. I have different types of documents in my couchdb
database. I want to specify an individual mapping for each type of
document.

I tried this way and is throwing an error.

PUT http://localhost:9200/_river/user/_mapping
{

"user" : {
  "properties" : {
    "first_name" : {
      "type" : "string",
      "search_analyzer" : "str_search_analyzer",
      "index_analyzer" : "str_index_analyzer"
    }
  }
  ,

"settings" : {
"analysis" : {
"analyzer" : {
"str_search_analyzer" : {
"tokenizer" : "keyword",
"filter" : ["lowercase"]
},

    "str_index_analyzer" : {
      "tokenizer" : "keyword",
      "filter" : ["lowercase", "substring"]
    }
  },

  "filter" : {
    "substring" : {
      "type" : "edgeNGram",
      "min_gram" : 2,
      "max_gram"  : 20
    }
  }
}

}
}
}

ERROR:
{"error":"MapperParsingException[Analyzer [str_search_analyzer] not found
for field [first_name]]","status":400}

Can any one help me how this can be rectified or any such kind of JSON
examples?

Also, I need to give mapping for few more fields like "last_name",
"organization" etc. How I can specify multiple fields in the above
example?

Thanks,
Srilatha

Hey,

1st:
Create your analyzer when you create your index: Something like the following (I did not check the exact syntax):
$ curl -XPUT 'http://localhost:9200/whateveryourindexis/' -d '{
"settings" : {
"analysis" : {
"analyzer" : {
"str_search_analyzer" : {
"tokenizer" : "keyword",
"filter" : ["lowercase"]
},

    "str_index_analyzer" : {
      "tokenizer" : "keyword",
      "filter" : ["lowercase", "substring"]
    }
  },

  "filter" : {
    "substring" : {
      "type" : "edgeNGram",
      "min_gram" : 2,
      "max_gram"  : 20
    }
  }
}

}

}'

See Elasticsearch Platform — Find real-time answers at scale | Elastic for details

2nd: you want to define a mapping for your type user under index "whateveryourindexis".
Don't send a mapping to the special index _river

Send something like:
$ curl -XPUT http://localhost:9200/whateveryourindexis/user/_mapping -d '{
"user" : {
"properties" : {
"first_name" : {
"type" : "string",
"search_analyzer" : "str_search_analyzer",
"index_analyzer" : "str_index_analyzer"
}
}'

See Elasticsearch Platform — Find real-time answers at scale | Elastic for details

Then, you can create the river.

Does it help?

Hi David,

I created analyzer, mapping and then river. It is working fine now.

Thank you very much for your help.
