1、 检索所有文档
GET bus/product/_search
2、 term检索
term是代表完全匹配，也就是精确查询，搜索前不会再对搜索词进行分词，所以我们的搜索词必须是文档分词集合中的一个，如果没有安装分词插件，汉字分词按每个汉字来分。
查询不到内容：
GET bus/product/_search
{
"query": {
"term": {
"producer": "公交"
}
}
}
producer中所有带“公”的文档都会被查询出来
GET bus/product/_search
{
"query": {
"term": {
"producer": "公"
}
}
}
3、 match检索
match查询会先对搜索词进行分词,分词完毕后再逐个对分词结果进行匹配，因此相比于term的精确搜索，match是分词匹配搜索
描述中带有机场酒店四个字的各种组合的文档都会被返回
GET bus/product/_search
{
"query": {
"match": {
"desc": "机场酒店"
}
}
}
4、 分页
GET bus/_search
{
"from": 0,
"size": 3,
"query": {
"match": {
"desc": "机场酒店"
}
}
}
GET bus/_search
{
"from": 0,
"size": 5,
"query": {
"match_all": {}
}
}
5、 过滤字段，类似select a,b from table中a,b
GET bus/_search
{
"_source": ["name","desc"] ,
"query": {
"match": {
"desc": "机场"
}
}
}
result:
{
"took" : 14,
"timed_out" : false,
"_shards" : {
"total" : 3,
"successful" : 3,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 12,
"max_score" : 2.1208954,
"hits" : [
{
"_index" : "bus",
"_type" : "product",
"_id" : "9",
"_score" : 2.1208954,
"_source" : {
"name" : "机场大巴A2线",
"desc" : "机机场场"
}
},
{
"_index" : "bus",
"_type" : "product",
"_id" : "10",
"_score" : 2.1208954,
"_source" : {
"name" : "机场大巴A2线",
"desc" : "机机场场"
}
},
{
"_index" : "bus",
"_type" : "product",
"_id" : "6",
"_score" : 0.62362677,
"_source" : {
"name" : "机场大巴A2线",
"desc" : "机机场场"
}
}
]
}
}
6、 检索结果显示版本
GET bus/_search
{
"version": true,
"from": 0,
"size": 3,
"query": {
"match": {
"desc": "机场酒店"
}
}
}
7、 按评分检索过滤
GET bus/_search
{
"version": true,
"min_score":"2.3", #大于2.3
"from": 0,
"size": 3,
"query": {
"match": {
"desc": "机场酒店"
}
}
}
8、 高亮关键字
GET bus/_search
{
"version": true,
"from": 0,
"size": 3,
"query": {
"match": {
"desc": "机场酒店"
}
}
, "highlight": {
"fields": {
"desc": {}
}
}
}
9、 短语匹配match_phrase
与match query类似，但用于匹配精确短语，分词后所有词项都要出现在该字段中，字段中的词项顺序要一致。
GET bus/_search
{
"query": {
"match_phrase": {
"name": "公交车122"
}
}
}
{
"took" : 4,
"timed_out" : false,
"_shards" : {
"total" : 3,
"successful" : 3,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : 3.4102418,
"hits" : [
{
"_index" : "bus",
"_type" : "product",
"_id" : "3",
"_score" : 3.4102418,
"_source" : {
"name" : "公交车122路",
"desc" : "从前兴路枢纽到东站",
"price" : 2,
"producer" : "公交集团",
"tags" : [
"单层",
"空调"
]
}
}
]
}
}
对比match
GET bus/_search
{
"query": {
"match": {
"name": "公交车122"
}
}
}
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 3,
"successful" : 3,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 3,
"max_score" : 5.3417225,
"hits" : [
{
"_index" : "bus",
"_type" : "product",
"_id" : "2",
"_score" : 5.3417225,
"_source" : {
"name" : "公交车5路",
"desc" : "从巫家坝到梁家河",
"price" : 1,
"producer" : "公交集团",
"tags" : [
"双层",
"普通",
"热门"
]
}
},
{
"_index" : "bus",
"_type" : "product",
"_id" : "3",
"_score" : 3.4102418,
"_source" : {
"name" : "公交车122路",
"desc" : "从前兴路枢纽到东站",
"price" : 2,
"producer" : "公交集团",
"tags" : [
"单层",
"空调"
]
}
},
{
"_index" : "bus",
"_type" : "product",
"_id" : "1",
"_score" : 2.1597636,
"_source" : {
"name" : "公交车5路",
"desc" : "从巫家坝到梁家河",
"price" : 1,
"producer" : "公交集团",
"tags" : [
"双层",
"普通",
"热门"
]
}
}
]
}
}
10、短语前缀查询match_phrase_prefix
match_phrase_prefix与match_phrase相同，只是它允许在文本中的最后一个词的前缀匹配
GET bus/_search
{
"query": {
"match_phrase_prefix": {
"name": "公交车1"
}
}
}
{
"took" : 3,
"timed_out" : false,
"_shards" : {
"total" : 3,
"successful" : 3,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : 6.8204837,
"hits" : [
{
"_index" : "bus",
"_type" : "product",
"_id" : "3",
"_score" : 6.8204837,
"_source" : {
"name" : "公交车122路",
"desc" : "从前兴路枢纽到东站",
"price" : 2,
"producer" : "公交集团",
"tags" : [
"单层",
"空调"
]
}
}
]
}
}
对比：
GET bus/_search
{
"query": {
"match_phrase": {
"name": "公交车1"
}
}
}
{
"took" : 0,
"timed_out" : false,
"_shards" : {
"total" : 3,
"successful" : 3,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
11、 多字段查询multi_match
GET bus/_search
{
"query": {
"multi_match": {
"query": "空港",
"fields": ["desc","name"]
}
}
}
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 3,
"successful" : 3,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 3,
"max_score" : 3.6836727,
"hits" : [
{
"_index" : "bus",
"_type" : "product",
"_id" : "16",
"_score" : 3.6836727,
"_source" : {
"name" : "机场大巴A2线",
"desc" : "空港",
"price" : 21,
"producer" : "大巴",
"tags" : [
"单层",
"空调",
"大巴"
]
}
},
{
"_index" : "bus",
"_type" : "product",
"_id" : "18",
"_score" : 3.5525968,
"_source" : {
"name" : "空港大巴A2线",
"desc" : "机场",
"price" : 21,
"producer" : "大巴",
"tags" : [
"单层",
"空调",
"大巴"
]
}
},
{
"_index" : "bus",
"_type" : "product",
"_id" : "19",
"_score" : 3.1757839,
"_source" : {
"name" : "空港大巴A2线",
"desc" : "空港快线",
"price" : 21,
"producer" : "大巴",
"tags" : [
"单层",
"空调",
"大巴"
]
}
}
]
}
}
12、范围检索，range查询用于匹配数值型、日期型或字符串型字段在某一范围内的文档。
GET bus/_search
{
"from": 0,
"size": 10,
"query": {
"range": {
"updateDate": {
"gte": "2018-12-01",
"lte": "2018-12-31",
"format": "yyyy-MM-dd"
}
}
}
}
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 3,
"successful" : 3,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 2,
"max_score" : 1.0,
"hits" : [
{
"_index" : "bus",
"_type" : "product",
"_id" : "13",
"_score" : 1.0,
"_source" : {
"name" : "机场大巴A2线",
"desc" : "机机场场",
"price" : 21,
"producer" : "机场大巴",
"tags" : [
"单层",
"空调",
"大巴"
],
"updateDate" : "2018-12-20"
}
},
{
"_index" : "bus",
"_type" : "product",
"_id" : "12",
"_score" : 1.0,
"_source" : {
"name" : "机场大巴A2线",
"desc" : "机机场场",
"price" : 21,
"producer" : "机场大巴",
"tags" : [
"单层",
"空调",
"大巴"
],
"updateDate" : "2018-12-01"
}
}
]
}
}
可以不加索引，表示搜索所有索引。
GET /_search
{
"from": 0,
"size": 10,
"query": {
"range": {
"updateDate": {
"gte": "2018-12-01",
"lte": "2018-12-31",
