Learning ElasticSearch: create an index Library

1, to create an index Library

• Use postman create an index library, I use es is 5.6.8 version, created different versions slightly different (usually more than 7.x)
• Json data transmission using postman

{
    "mappings":{
        "articles":{
            "properties":{
                "id":{
                    "type":"long",
                    "store":true
                },
                "title":{
                    "type":"text",
                    "store":true,
                    "index":"analyzed",
                    "analyzer":"standard"
                },
                "content":{
                    "type":"text",
                    "store":true,
                    "index":"analyzed",
                    "analyzer":"standard"
                }
            }
        }
    }
}

• blog1 here is our index database name, here is equivalent to a database. put the request is meant to create. mapping is a keyword, referring to the maps, articles refers to the type, the equivalent of a database table, properties refers to a field equivalent to fields in the database.
• Get the return result
  
• Creating success
  
• Also directly can create an index es graphical interface, click New Index
  
• This index is created inside, mapping is empty, we can use to set mapping postman again
  
  

2, delete the index database

• Mode change request to delete
