Elasticsearch_初始化配置

Java代码  

1. 构建ES集群环境经常用到的配置：  
2. 1.action.auto_create_index --配置是否自动创建索引（true OR false);  
3. 2.gateway.type -- (fs, none, local);  
4. 3.cluster.routing.schedule 如（50ms)， 发现新节点时间  
5.   
6.   
7.   
8. Settings settings = settingsBuilder()  
9.                 .put("discovery.type", "zen") //发现集群方式  
10.                 .put("discovery.zen.minimum_master_nodes", 2) //最少有2个master存在  
11.                 .put("discovery.zen.ping_timeout", "200ms") //集群ping时间，太小可能会因为网络通信而导致不能发现集群  
12.                 .put("discovery.initial_state_timeout", "500ms")  
13.                 .put("gateway.type", "local")  
14.                 .put("index.number_of_shards", 1)  
15.                 .put("action.auto_create_index", false)  
16.                 .put("cluster.routing.schedule", "50ms")  
17.                 .build();  
18.   
19.   
20.   
21. 改变shards数目：  
22.   
23. client.admin().indices().prepareUpdateSettings("test").setSettings(settingsBuilder().put("index.number_of_replicas", 2)).execute().actionGet();  

使用Mongodb River时，可设置 river.mongodb: TRACE 打开日志。 

Html代码  

1. ES常量设置：  
2. index.cache.query.parser.type 查询分析缓存类型， 分为：JVM级别， resident的和NULL。  
3. index.cache.field.max_size 设置大小，配置为soft时用。  
4. index.cache.field.expire 可设置为null,表示永不过期。  
5. index.cache.field.type 值集合：{resident, soft, none} 分别为常驻式、驱逐式、无缓存  
6. index.cache.filter.type (none, weighted)  
7. index.codec.postings_format.type (BloomFilterPostingsFormatProvider,DirectPostingsFormatProvider, MemoryPostingsFormatProvider, Lucene40PostingsFormatProvider, Pulsing40PostingsFormatProvider)  
8. cluster.routing.operation.type  
9. cluster.routing.operation.hash.type （DjbHashFunction， SimpleHashFunction）  
10. index.analysis.char_filter  
11. index.cache.id.type (SimpleIdCache)  
12.   
13. index.merge.policy.type

21.                 "index.merge.policy.max_merge_docs",  
22.                 "index.merge.policy.merge_factor",  
23.                 "index.compound_format"  
24.   
25.                 "index.merge.policy.expunge_deletes_allowed",  
26.                 "index.merge.policy.floor_segment",  
27.                 "index.merge.policy.max_merge_at_once",  
28.                 "index.merge.policy.max_merge_at_once_explicit",  
29.                 "index.merge.policy.max_merged_segment",
