安装方式大概分为两种:
环境说明:
我下载的es版本是:elasticsearch-1.7.4.tar.gz,这里我是用的ik版本是elasticsearch-rtf-1.0.0.zip解压后得到的elasticsearch-analysis-ik-1.2.6.jar文件。
自行编译的步骤如下:
1.到https://github.com/medcl/elasticsearch-analysis-ik页面下载elasticsearch-analysis-ik-x.x.x.zip压缩包;
2.解压elasticsearch-analysis-ik-x.x.x.zip,然后进行elasticsearch-analysis-ik-x.x.x目录;
3.使用maven进行打包,得到elasticsearch-analysis-ik-x.x.x.jar(然而我并不会使用maven进行打包,所以我没用这种方式);
4.进行elasticsearch-1.7.4/plugins目录,创建目录analysis-ik,并把你编译好的elasticsearch-analysis-ik-x.x.x.jar放置到此目录;
5.将你下载的elasticsearch-analysis-ik-x.x.x.zip解压后的config目录下的ik目录复制到elasticsearch-1.7.4/config目录;
6.配置elasticsearch-1.7.4/config目录下的elasticsearch.yml文件,在文件尾部加入如下代码:
index: analysis: analyzer: ik: alias: [ik_analyzer] type: org.elasticsearch.index.analysis.IkAnalyzerProvider ik_max_word: type: ik use_smart: false ik_smart: type: ik use_smart: true
或简单配置:
index.analysis.analyzer.ik.type : "ik"
7.重新启动es;
我使用的就是这种方式,第一种方式我并没有进行测试,所以暂时不保证正确,着重说明一下第二种方式,步骤如下:
1.到这里https://github.com/medcl/elasticsearch-rtf/releases下载rtf版的es,我下载的是elasticsearch-rtf-1.0.0.zip;
2.解压elasticsearch-rtf-1.0.0.zip压缩包;
3.将elasticsearch-rtf-1.0.0/plugins/analysis-ik目录,复制到elasticsearch-1.7.4/plugins得到elasticsearch-1.7.4/plugins/analysis-ik;
4.将elasticsearch-rtf-1.0.0/config/ik复制到elasticsearch-1.7.4/config/得到elasticsearch-1.7.4/config/ik;
5.编辑elasticsearch-1.7.4/config/elasticsearch.yml文件,在文件尾部加入以下内容:
index: analysis: analyzer: ik: alias: [ik_analyzer] type: org.elasticsearch.index.analysis.IkAnalyzerProvider ik_max_word: type: ik use_smart: false ik_smart: type: ik use_smart: true
或简单配置:
index.analysis.analyzer.ik.type : "ik"
6.重新启动es;
创建索引:
curl -XPUT http://localhost:9200/index
创建映射:
curl -XPOST http://localhost:9200/index/fulltext/_mapping -d' { "fulltext": { "_all": { "analyzer": "ik_max_word", "search_analyzer": "ik_max_word", "term_vector": "no", "store": "false" }, "properties": { "content": { "type": "string", "store": "no", "term_vector": "with_positions_offsets", "analyzer": "ik_max_word", "search_analyzer": "ik_max_word", "include_in_all": "true", "boost": 8 } } } }'
为索引添加一些内容:
curl -XPOST http://localhost:9200/index/fulltext/1 -d' {"content":"美国留给伊拉克的是个烂摊子吗"} ' curl -XPOST http://localhost:9200/index/fulltext/2 -d' {"content":"公安部:各地校车将享最高路权"} ' curl -XPOST http://localhost:9200/index/fulltext/3 -d' {"content":"中韩渔警冲突调查:韩警平均每天扣1艘中国渔船"} ' curl -XPOST http://localhost:9200/index/fulltext/4 -d' {"content":"中国驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首"} '
进行高亮查询:
curl -XPOST http://localhost:9200/index/fulltext/_search -d' { "query" : { "term" : { "content" : "中国" }}, "highlight" : { "pre_tags" : ["", " ", ""], "fields" : { "content" : {} } } } '"], "post_tags" : ["
查询结果:
{"took":31,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":2,"max_score":0.61370564,"hits":[{"_index":"index","_type":"fulltext","_id":"4","_score":0.61370564,"_source": {"content":"中国驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首"} ,"highlight":{"content":["中国 驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首"]}},{"_index":"index","_type":"fulltext","_id":"3","_score":0.61370564,"_source": {"content":"中韩渔警冲突调查:韩警平均每天扣1艘中国渔船"} ,"highlight":{"content":["中韩渔警冲突调查:韩警平均每天扣1艘中国 渔船"]}}]}}
或者你可以直接在浏览器地址栏进行测试:http://localhost:9200/index/_analyze?analyzer=ik&pretty=true&text=%E6%88%91%E6%98%AF%E4%B8%AD%E5%9B%BD%E4%BA%BA
注意:如果你的版本不对应,可能会出现如下错误:
{"error":"IndexCreationException[[index] failed to create index]; nested: ElasticsearchIllegalArgumentException[failed to find analyzer type [ik] or tokenizer for [ik_max_word]]; nested: NoClassSettingsException[Failed to load class setting [type] with value [ik]]; nested: ClassNotFoundException[org.elasticsearch.index.analysis.ik.IkAnalyzerProvider]; ","status":400}
