我從我的用戶那里得到一個代表彈性請求的字串。可以有以下型別的請求：
單項：TERM:MATCH_TERM;
用AND分隔的幾個術語：TERM:MATCH_TERM AND TERM:MATCH_TERM AND TERM:MATCH_TERM;
由OR分隔的幾個術語：TERM:MATCH_TERM OR TERM:MATCH_TERM OR TERM:MATCH_TERM;
由AND和OR分隔的幾個TERM:MATCH_TERM AND TERM:MATCH_TERM OR TERM:MATCH_TERM AND TERM:MATCH_TERM OR TERM:MATCH_TERM AND TERM:MATCH_TERM術語：
OR操作員優先于操作AND員
接下來我決議這個字串并得到我的不同術語的串列。
我現在想使用這個串列來構建我的彈性查詢。我知道我將不得不使用復雜查詢的語法：bool. （我使用 elastic 的 javascript 客戶端提出我的請求）
據我了解，must過濾器將允許我執行AND過濾器should將允許我執行OR。
在我們有的情況下TERM1:MATCH_TERM1 AND TERM2:MATCH_TERM2 OR TERM3:MATCH_TERM3 AND TERM4:MATCH_TERM4 OR TERM5:MATCH_TERM5 AND TERM6:MATCH_TERM6：
正確的語法是這樣的：
"query":{
"bool":{
"should":[
"must":[
{"terms":{"TERM1":"MATCH_TERM1"}}
] ,
"must":[
{"terms":{"TERM2":"MATCH_TERM2"}}
] ,
],
"should":[
"must":[
{"terms":{"TERM3":"MATCH_TERM3"}}
] ,
"must":[
{"terms":{"TERM4":"MATCH_TERM4"}}
] ,
],
"should":[
"must":[
{"terms":{"TERM5":"MATCH_TERM5"}}
] ,
"must":[
{"terms":{"TERM6":"MATCH_TERM6"}}
] ,
],
}
}
