elasticsearch three basic query (the English word) match the query

#match查询
#match query知道分词器的存在，会对filed进行分词操作, 然后再查询
GET /ib3/user/_search 
{ 
  "query":{ 
    "match":{ "name": "zhaoliu" }
  }
}
GET /lib3/user/_search 
{ 
  "query":{ 
    "match":{ "age": 20}
  }
}
#match_all:查询所有文档
GET /ib3/user/_search
{ 
  "query":{"match_all":{}}
}
#multi_match:可以指定多个字段
GET /ib3/user/_search 
{ 
  "query":{ 
    "multi_match": { 
      "query": "Ilyou", 
      "fields": ["interests" ,"name"]
    }
  }
}
#match_ phrase:短语匹配查询
#ElasticSearch引擎首先分析(analyze) 查询字符串，
#从分析后的文本中构建短语查询，
#这意味着必须匹配短语中的所有分词，
#并且保证各个分词的相对位置不变:
GET lib3/user/_search 
{ 
  "query":{
    "match_phrase":{"interests": "duanlian, shuoxiangsheng" }
  }
}

Try a query term, did not find, because the term is not aware of the word, would be "name": "zhaoliu zhaoming" as a keyword in the keyword index inverted index is not, so there is no found

 

 The same query terms do not know word (in inverted index "name": "zhaoliu zhaoming" will be seen as a keyword in the inverted index is an index does not exist) and an array of query terms, does not support a single string query

#match query know the word's Existence, will be filed segmentation operation, and then specify a single query #match query field conditions

GET /lib3/user/_search
{
  "query":{
    "match":{"name": "zhaoliu zhaoming"}
  }
}

{
  "took" : 38,
  "timed_out" : false,
