在上一篇中我们介绍了DSL相关的知识，接下来我们将会学习elasticsearch的结构化查询，同时也实践一下上一篇的DSL的查询用法
什么是结构化搜索?
从《Elasticsearch权威指南》上摘取部分解释如下:
结构化搜索是指查询包含内部结构的数据。日期，时间，和数字都是结构化的：它们有明确的格式给你执行逻辑
操作。一般包括比较数字或日期的范围，或确定两个值哪个大。文本也可以被结构化。一包蜡笔有不同的颜色:
红色 ， 绿色 ， 蓝色 。一篇博客可能被打上 分布式 和 搜索 的标签。电子商务产品有商品统一代码（UPCs）
或其他有着严格格式的标识。
通过结构化搜索，你的查询结果始终是是或非；是否应该属于集合。结构化搜索不关心文档的相关性或分数，
它只是简单的包含或排除文档。这必须是有意义的逻辑，一个数字不能比同一个范围中的其他数字 更多。它只能
包含在一个范围中或不在其中。类似的，对于结构化文本，一个值必须相等或不等。这里没有更匹配的概念。
从上面的定义我们可以看出来结构化查询最重要的就是是否匹配么人并不是很关心相关性和分值计算。所以接下来我们将会一一介绍不同的结构化查询。
Term查询
term 主要用于查找精确值，由于不需要计算分值，而且可以被缓存，所以速度很快,而且term查询主要针对的是数字，日期，布尔值或 not_analyzed 的字符串(未经分析的文本数据类型)。
首先我们使用term查询一下:
GET bank/_search
{
"query": {
"term": {
"firstname": {
"value": "Burton"
}
}
},
"profile": "true"
}
返回结果:
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 0,
"relation" : "eq"
},
"max_score" : null,
"hits" : [ ]
},
"profile" : {
"shards" : [
{
"id" : "[jW8PbSdhTOOpESX13DRBJQ][bank][0]",
"searches" : [
{
"query" : [
{
"type" : "TermQuery",
"description" : "firstname:Burton",
"time_in_nanos" : 8729,
"breakdown" : {
"set_min_competitive_score_count" : 0,
"match_count" : 0,
"shallow_advance_count" : 0,
"set_min_competitive_score" : 0,
"next_doc" : 0,
"match" : 0,
"next_doc_count" : 0,
"score_count" : 0,
"compute_max_score_count" : 0,
"compute_max_score" : 0,
"advance" : 0,
"advance_count" : 0,
"score" : 0,
"build_scorer_count" : 2,
"create_weight" : 7274,
"shallow_advance" : 0,
"create_weight_count" : 1,
"build_scorer" : 1455
}
}
],
"rewrite_time" : 1222,
"collector" : [
{
"name" : "SimpleTopScoreDocCollector",
"reason" : "search_top_hits",
"time_in_nanos" : 3132
}
]
}
],
"aggregations" : [ ]
}
]
}
}
我们发现结果好像并不尽如人意，那么我们再试一个,这次我们把他修改成年龄字段搜索:
GET bank/_search
{
"query": {
"term": {
"age": {
"value": 36
}
}
},
"profile": "true"
}
返回结果:
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 52,
"relation" : "eq"
},
"max_score" : 1.0,
"hits" : [
{
"_index" : "bank",

根据上面的结果，我们再一次验证了，term查询只针对精确值、布尔值、日期以及未经分析的字段，而如果我们用term去查询一些单词或者句子等，就会匹配不到对应的值，为什么呢？官网其实也给出了解释，在下图中就可以看到，其实是因为我们es默认的标准分词器可能将我们要查询的句子或者单词变成小写了，或者拆分了，而我们的term查询又是精确查询，所以不会分析我们的搜索字段的，从而导致term查询一些单词和短语时，很难得到满意的结果。当然这也是官方提醒我们要避免的,官方建议我们使用match来匹配查询一些单词和短语，效果要比term好。

Terms查询
terms查询其实就是类似整合多个term查询。如例子所示:
GET bank/_search
{
"query": {
"terms": {
"age": [36,27]
}
},
"profile": "true"
}
返回结果:

"failed" : 0

"hits" : {
"total" : {
"value" : 91,
"relation" : "eq"
},
"max_score" : 1.0,
"hits" : [

当然在term中需要注意的在这里同样需要。terms也是同样是精确查询。这里提一嘴terms lookup的用法，先看lookup的例子:
GET bank/_search
{
"query": {
"terms": {
"age": {
"index" : "bank",
"id" : "342",
"path" : "age"
}
}
},
"profile": "true"
}
返回结果:

"timed_out" : false,

"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 52,
"relation" : "eq"
},
"max_score" : 1.0,
"hits" : [
{
"_index" : "bank",

我理解的意思就是查询与指定文档id下的指定的字段的值一样的文档有哪些。效率虽然高，但是限制也比较多，可自行查看官网描述的相关限制,传送门
range查询
range查询即范围查询，主要包括数字查询和日期查询，当然也可以查询文本，但是要将search.allow_expensive_queries设置为true。
查询数字
查询的结构如下:
GET bank/_search
{
"query": {
"range": {
"age": {
"gte" : 27,
"lt" : 36
}
}
},
"profile": "true"
}
其中范围查询的参数有:
gte:大于等于
gt:大于
lt:小于
lte:小于等于
format:主要用来格式化日期的
time_zone:时区
查询数字的返回结果为:
{
"took" : 15,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 436,
"relation" : "eq"
},
"max_score" : 1.0,
"hits" : [
{
"_index" : "bank",
"_type" : "account",
"_id" : "13",
"_score" : 1.0,
"_source" : {
"account_number" : 13,
"balance" : 32838,
"firstname" : "Nanette",
"lastname" : "Bates",
"age" : 28,
"gender" : "F",

日期范围
由于这里我们的例子中没有日期相关的数据，所以我们再导入一份含有日期数据的文件到es中。即logs.jsonl
同样通过命令行导入的方式:
curl -H 'Content-Type: application/x-ndjson' -s -XPOST ip:9200/_bulk --data-binary @logs.jsonl
因为这里导入的数据比较大，可能会报数据量过大的错误，此时需要修改es的内存大小，因为我们在前面使用docker安装es的时候，启动的时候，设置了es的java虚拟机内存使用大小为256m，所以这里我们需要将es集群关闭之后，重新启动，如下所示:
docker stop ES01
docker rm ES01
docker run -d --restart=always -e ES_JAVA_OPTS="-Xms1g -Xmx1g" -p 9200:9200 -p 9300:9300 -v /data/es/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /data/es/node1/data:/usr/share/elasticsearch/data -v /data/es/node1/plugins:/usr/share/elasticsearch/plugins --name ES01 elasticsearch:7.9.3
我们将这句-e ES_JAVA_OPTS="-Xms1g -Xmx1g"已经修改为1g了，然后启动，其他两个节点同样需要这样的操作。
最后导入数据即可。
从图中可知我们已经导入成功了，
这里我们开始学习range的查询日期用法:
在这里我们查询日志的utc_time
GET logstash-2015.05.19/_search
{
"query": {
"range": {
"utc_time": {
"gte" : "2015-05-19T04:29:38.264Z",
"lte" : "2015-05-30T04:29:38.264Z"
}
}
}
}
返回结果:

准确的输出了日期2015-05-19T04:29:38.264Z与2015-05-30T04:29:38.264Z之间的数据。
小结
关于range的查询基本就这么多，还有部分关于字符串的，过于简单就不做详细的叙述，因为字符串的查询是直接利用的字典序查询，不如是用其他方式直接查询字符串。还有关于ip的范围查询，但是实在聚合查询中体现的，在range中好像并没法使用。
Exists查询
exists查询的主要意思是字段是否存在值，如果不存在值，则不会被查询出来，如果有值，则会被查询出来，null的情况下也不会被查询出来。
这里我就直接查询了，因为数据量比较大，所以只展示用法，数据是否为null等就算了，嘿嘿

总结
结构化查询的第一部分基本就这么多，后面还会学习第二部分的，关于模糊查询方面的。
