数据准备
# 创建索引
PUT /lib1
{

"number_of_shards": 5
, "number_of_replicas": 0
},

}
}
# 添加数据

# 简单条件查询
GET /lib1/user/_search?q=name:lisi
GET /lib1/user/_search?q=interests:changge&sort=age:desc
term查询和terms查询
term query回去倒排索引中寻找确切的term,它并不知道分词器的存在。这种查询适合keyword、numeric、date。
term:查询某个字段含有某个关键词的文档
GET /lib1/user/_search
{
"query": {
"term": {
"name": "zhaoliu"
}
}
}

GET /lib1/user/_search
{
"query": {
"match_all": {}
}
}multi_match:指定多个字段
GET /lib1/user/_search
{
"query": {
"multi_match": {
"query": "changge",
"fields": ["interests","name"]
}
}
}match_phrase:短语匹配查询
ElasticSearch引擎首先分析查询字符串,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 /lib1/user/_search
{
"query": {
"match_phrase": {
"interests": "duanlian,changge"
}
}
}

"age": 20,
"birthday": "1998-10-12",
"interests": "xi huan hejiu,duanlian,changge"
}
}
]
}
}指定查询字段
# 指定查询字段
GET /lib1/user/_search
{
"_source": {
"includes": ["name","adress"]
},
"query": {
"match_all": {}
}
}
# 排除查询字段
GET /lib1/user/_search
{

"excludes": ["name","adress"]
},
"query": {
"match_all": {}
}
}
# 通配符匹配查询字段
GET /lib1/user/_search
{

{

排序
使用sort实现排序:desc降序,asc升序
GET /lib1/user/_search
{
"query": {
"match_all": {}
},
"sort": [
{
"age": {
"order": "desc"
}
}
]
}
GET /lib1/user/_search
{
"query": {
"match_all": {}
},
"sort": [
{
"age": {
"order": "asc"
}
}
]
}
前缀匹配
GET /lib1/user/_search
{
"query": {
"match_phrase_prefix": {
"name": {
"query": "zhao"
}
}
}
}
范围查询
# []
GET /lib1/user/_search
{
"query": {
"range": {
"birthday": {
"from": "1990-10-10",
"to": "2018-05-01"
}
}
}
}
# ()
GET /lib1/user/_search
{
"query": {
"range": {
"birthday": {
"from": "1995-10-12",
"to": "1998-10-12",
"include_lower":false,
"include_upper":false
}
}
}
}
GET /lib1/user/_search
{
"query": {
"range": {
"age": {
"gte": 20,
"lte": 28
}
}
}
}
wildcard查询
允许使用通配符*和?来进行查询
*代表0个或多个字符
?代表任意一个字符
GET /lib1/user/_search
{
"query": {
"wildcard": {
"name": {
"value": "li?i"
}
}
}
}
GET /lib1/user/_search
{
"query": {
"wildcard": {
"name": "zhao*"
}
}
}
fuzzy实现模糊查询
value:查询的关键字
boost:查询的权值,默认值是1.0
min_similarity:设置匹配的最小相似度,默认值是0.5,对于字符串,取值为0-1(包括0和1);对于数值,取值可能大于1;对于日期型取值为1d,1m等。
prefix_length:指名区分词项的共同前缀长度,默认是0
max_expansion:查询中的词项可以扩展的数目,默认可以无限大
# 查询
GET /lib1/user/_search
{
"query": {
"fuzzy": {
"name":"zhliuwu"
}
}
