Mapping detailed 4 (mapping setting)

Mapping type

The mapping settings typically occur in:

1. When adding a new index, add the mapping type to set the fields mapping

PUT Twitter {"Mappings": {    "Tweet": {      "Properties": {        "message": {          "type":"string"        }      }    }  }}

2. Add a new mapping type for index, set the mapping of fields

PUT twitter/_mapping/User {  "properties": {    "  Name": {      "type""string "     }  }}

3. Add a new fields mapping setting for the existing mapping type

PUT twitter/_mapping/Tweet {  "properties": {    "  User_name": {      "type""string "    }  }}

Setup mode

1. Give the full mapping setting in the PUT request body

PUT Twitter {"Mappings": {//Mappings object, description for mapping settings    "Tweet": {//Specify mapping Type      "Properties": {//Specify the properties setting for the mapping type        "message": {//to set the mapping of a field message          "type":"string"              //mappingparameter Configuration        }      }    }  }}

When you add index, you can also set the index, in addition to setting the mapping type, such as configuring a custom analyzer, number of index shards, etc.

PUT/my_index{"Settings": {    " Analysis": {      "Analyzer": {        "AutoComplete": {           "type":"Custom",          "Tokenizer":" Standard",          "Filter": [            "lowercase",            "Autocomplete_filter"          ]        }      }    }  },  "Mappings": {    "My_type": {      "Properties": {        "text": {          "type":"string",          "Analyzer":"AutoComplete"        }      }    }  }}

2. Specify the type in the PUT request URI and give the type's settings in the request body

PUT twitter/_mapping/User {  "properties": {                   // Specify mapping The properties of type set    "name": {                       // Set the mapping of the field message       "type""string "               parameter Configuration     }  }}

3. A complete mapping type setting includes: Meta-fields and fields or properties settings

PUT my_index{"Mappings": {    "Type_1": {       "Properties": {...}//Properties Settings    },    "type_2": {       "_all": {//meta-fields Settings        "enabled":false      },      "Properties": {...} }  }}
