我尝试修改现有查询字符串以筛选指定的条件：现在查询字符串如下：

String bodycontent="{"
                +"  \"_source\": [\"@timestamp\",\"eqpid\",\"lotid\",\"stageid\",\"srvmethod\",\"parm_1\",\"apcack\",\"description\",\"host\",\"path\",\"action\"],"
                +"  \"query\": {"
                +"    \"query_string\" : {"
                +"        \"query\":\" lotid:"+q_lotid+" AND "+host_type+"\"}"
                +"  },"
                +"  \"sort\" : [{\"@timestamp\" : { \"order\" : \"desc\" }}]"
                +"}";

我想更改以下查询条件：

query :
type:ams_log AND (alm_source:K*) AND (alm_id:TCS00004 OR alm_id:TCS00005 OR alm_id:TCS00007 OR alm_id:TCS00008 OR alm_id:TCS00009 OR alm_id:TCS00010 OR alm_id:TCS00011 OR alm_id:TCS00012 OR alm_id:TCS00013 OR alm_id:TCS00020 OR alm_id:TCS00024 OR alm_id:TCS00032)

但是我不知道如何用斜杠修改查询字符串 \ 和双引号 " . 我找不到规则，谢谢！

斜杠- \\ 引用- \" ```
System.out.println("\ "hello"");

输出： `\ "hello"` 关于您的查询，似乎key和value都必须在引号之间 `"key":"value"` ```
String lotId="2020_A_88";
String type="apples";
String queryPart = "\"lotId\":\""+lotId+"\" AND \"type\":\""+type+"\"";
System.out.println(queryPart);
``` `"lotId":"2020_A_88" AND "type":"apples"` ```
String example = String.format("Slash-> %s , Quotes-> %s", "\\" ,"\"name\""); 
System.out.println(example);
``` `Slash-> \ , Quotes-> "name"` ```
String s = "\\";
String q = "\"name\"";
System.out.println("Slash-> "+s+" , Quotes-> "+q);
``` `Slash-> \ , Quotes-> "name"`
