elasticsearch java动态设置mapping并指定分词器
//创建索引 client.admin().indices().prepareCreate("twitter").execute().actionGet(); //配置mapping XContentBuilder mapping = XContentFactory.jsonBuilder().startObject() .startObject("tweet") .startObject("properties") .startObject("user").field("type", "string").field("store", "yes").field("index", "not_analyzed").endObject() .startObject("message").field("type", "string").field("store", "yes").field("index", "analyzed").endObject() .startObject("postDate").field("type", "date").endObject() // .startObject("content").field("type","string").field("store","yes").field("analyzer","ik").field("search_analyzer","ik_smart").endObject() .startObject("content").field("type", "string").field("store", "yes").field("analyzer", "ik").endObject() .endObject() .endObject() .endObject(); PutMappingRequest mappingRequest = Requests.putMappingRequest("twitter").type("tweet").source(mapping); client.admin().indices().putMapping(mappingRequest).actionGet(); // 批量插入数据 BulkRequestBuilder bulkRequest = client.prepareBulk(); IndexRequest request = client.prepareIndex("twitter", "tweet", "1").setSource(json).request(); IndexRequest request2 = client.prepareIndex("twitter", "tweet", "2").setSource(json2).request(); bulkRequest.add(request); bulkRequest.add(request2); bulkRequest.execute().actionGet(); client.close();
index的值只有三种(no,not_analyzed,analyzed)
https://www.elastic.co/guide/en/elasticsearch/reference/2.4/mapping-index.html
no:不添加到索引
not_analyzed:添加到索引不分词
analyzed : 添加到索引并分词
