我在#caseIndia之类的驼峰案例中有一个带有标签的标签。现在，单击此主题标签后，它将获取其中包含“#teamIndia”的所有结果，首先应显示“#teamIndia”的结果，然后显示“teamIndia”的结果，然后显示“team India”的结果，然后显示“team”或“印度”等。
我在做什么:
搜索文字:
“#teamIndia”，“＃NEWYORK”，“＃profession”，“＃2016”

文档示例:-

POST /clip/Clip/3 {"id" : 2, "description" : "bikes in DUBAI TheBestAndTheBeast profession"}
POST /clip/Clip/3 {"id" : 2, "description" : "Know how a software engineer surprised his wife! <a href="search/clips?q=%23theProvider&source=hashtag" ng-click="handleModalClick()"> #theProvider </a> rioOlympic <a href="search/clips?q=%23DUBAI&source=hashtag" ng-click="handleModalClick()"> #DUBAI </a> <a href="search/clips?q=%23TheBestAndTheBeast&source=hashtag" ng-click="handleModalClick()"> #TheBestAndTheBeast </a> <a href="search/clips?q=%23rioOlympic&source=hashtag" ng-click="handleModalClick()"> #rioOlympic </a>"}
**搜索查询**
GET clip/_search
{
"size": 100,
"query": {
"filtered": {
"query": {
"bool": {
"must":
{
"query_string": {
"fields": [
"description.hashtag"
],
"query": "teamIndia"
}
},
"should": {
"match":
{ "description.raw": "#teamIndia"}
}
}
}
}
}
}
异常(exception)结果:
“#teamIndia”，
“teamIndia”，
“印度队”，
“团队”，
“印度”，
与其他测试关键字相似。
最佳答案
原始帖子中的查询无法按预期运行的原因之一是因为description.raw是not_analyzed。
结果，#teamIndia将永远不会与description: "Animals and Pets and #teamIndia"匹配文档，因为description.raw将包含
未分析的词Animals and Pets and #teamIndia而不是#teamIndia
假设您拥有的文档类似于OP中的第二个示例。
示例:
{"id" : 2, "description" : "Animals and Pets and #teamIndia"}
或者
{"id":7,"description":"This <a href="search/clips?q=%23teamIndia&source=hashtag">#teamIndia</a>"}
然后，您应该能够按照以下顺序对文档进行排名:
1)包含“#teamIndia”的描述，
2)包含“teamIndia”的描述
3)包含“团队印度”的描述
4)包含“印度”的说明
