Distributed Search Elasticsearch Chinese word segmentation integration

Elasticsearch official only provide SMARTCN this Chinese word-breaker, the effect is not very good, fortunately, there are MEDCL great God (one of the earliest research es in China) wrote two Chinese word-breaker, one is IK, one is mmseg, the following describes the use of the two, respectively, Actually all the same, first install the plugin, command line:

Word Segmentation Configuration

IK participle configuration, added in Elasticsearch.yml file

Index: Analysis
  :                   
    Analyzer:      
      ik:
          alias: [Ik_analyzer]
          type: Org.elasticsearch.index.analysis.IkAnalyzerProvider

Or

Index.analysis.analyzer.ik.type: "Ik"

These two sentences have the same meaning.
Mmseg word configuration, but also in the Elasticsearch.yml file

Index: Analysis
  :
    Analyzer:
      mmseg:
          alias: [News_analyzer, Mmseg_analyzer]
          type: Org.elasticsearch.index.analysis.MMsegAnalyzerProvider

Or

Index.analysis.analyzer.default.type: "Mmseg"

Mmseg participle There are some more personalized parameters set as follows

Index: Analysis
  :
    tokenizer:
      mmseg_maxword:
          type:mmseg
          seg_type: "Max_word"
      mmseg_ Complex:
          type:mmseg
          seg_type: "Complex" mmseg_simple: type:mmseg seg_type
          : "Simple"

This configuration completes after the plug-in installation is completed, boot es will load plug-ins.

Define Mapping

You can define a word breaker when you add an index to the mapping

{'
   page ': {' properties ': {'
         title ': {'
            type ': ' String ',
            ' indexanalyzer ': ' ik ',
            ' Searchanalyzer ": Ik"
         },
         "content": {
            "type": "string",
            "Indexanalyzer": "Ik",
            " Searchanalyzer ': ' Ik '}}}

Indexanalyzer is the word breaker used for indexing, Searchanalyzer for use in search.

The Java mapping code is as follows:

Xcontentbuilder content = Xcontentfactory.jsonbuilder (). StartObject ().
        startobject ("page").
          StartObject (" Properties ")       
            . StartObject (" title "). Field ("
              type "," string ").           
              field (" Indexanalyzer "," ik ").
              field ("Searchanalyzer", "IK")
            . EndObject () 
            . StartObject ("code")
              . Field ("Type", "string")         
              . Field ("Indexanalyzer", "ik").
              Field ( "Searchanalyzer", "IK")
            . EndObject (). EndObject (). EndObject ().
       EndObject ()

After the definition of the operation index will be the designated word breaker to the word.

Test participle can call the following API, note that IndexName is the index name, casually specify an index on the line
http://localhost:9200/indexname/_analyze?analyzer=ik&text= Test Elasticsearch Word breaker
