REST API (CREATE INDEX, retrieve document)

The following is a brief introduction to the usage of the set of APIs provided by Elasticsearch:,

1. Create an index PUT

The following creates an index JIU3, which overrides the configuration information, otherwise the default of 5 shards and a copy, the mapping is written in a TYPE:LVH, and two fields. Of course, these are not necessary in curly braces.

1Curl-xput http://192.168.100.15:9200/jiu3/-d ' {2     "Settings":{3         "Index":{4             "Number_of_shards":1,5             "Number_of_replicas":06         }7     },8     "Mappings":{9         "LVH":{Ten             "Properties":{ One                 "name":{ A                     "type":"string"}, -                 " Age":{ -                     "type":"Long"} the             } -         } -     } -}'

2. Add a document POST

When you add a document, you can add it in the existing type, or you can create a new type to add the document. The unique identifier (_ID) can be written without writing.

1 curl-xpost http://192.168.100.15:9200/JIU3/LIH/1-d ' {2     '  Name":"Huan"}'

3. Get the document get

Pretty is displayed in JSON format

1 curl-xget http://192.168.100.15:9200/jiu3/lih/1?pretty

4. Retrieving a document GET

There are a variety of ways to search, simply cite a few examples:

1 curl-xget http://192.168.100.15:9200/jiu3/lih/_search?pretty

1 curl-xget http://192.168.100.15:9200/jiu3/_search?pretty&q=name:huan
