Question

我正在尝试在弹性搜索查询下面实现

**- A full example of POM file.**
Command to Build All **Jrxml** to **Jasper File** in maven
If you used eclipse then right click on the project and Run as maven Build and add goals antrun:run@compile-jasper-reports 
compile-jasper-reports is the id you gave in the pom file.

**<id>compile-jasper-reports</id>**

}

如何在java中实现它。我想过这样做

{
"query": {
    "bool": {
        "must": [
            {"match": {"collegeName": "XXXX"}},
            {"match": {"userType": "STUDENT"}},
            {"match": {"details.blocklisted":"TRUE"}}
            ]
    }
}

有更好的方法吗???? 帮助！

Answer 1

是，

使用搜索模板（ES official doc）。它就像一个存储过程。具有可替换变量的查询。另外，更改查询只是一个简单的更新。事先创建模板（POST / _search / template / templateName {BODY}）然后你可以调用它（POST / twitter / tweet / _search / templateName {包含动态变量的BODY}）。

同样在JAVA中

Map<String, Object> params = new HashMap<String, Object>();
params.put("search_term", "elasticsearch");
params.put("since", "now-30d");

Template template = new Template("tweets", ScriptService.ScriptType.FILE, 
MustacheScriptEngineService.NAME, null, params);
SearchRequestBuilder request = 
client.prepareSearch(INDEX).setTemplate(template);

SearchResponse response = request.execute（）。actionGet（）;

Answer 2

您可以使用MultiMatchQueryBuilder之类的

SearchQuery searchQuery = new NativeSearchQueryBuilder()
              .withQuery(multiMatchQuery("college")
                .field("collegeName")
                .field("userType")
                .type(MultiMatchQueryBuilder.Type.BEST_FIELDS))
              .build();

如何在elasticsearch中的bool查询中放置多个匹配查询
