1铐姚、知識點：match query底層會自動轉(zhuǎn)換為term+should/must方式
2、實例剖析
（1）普通match如何轉(zhuǎn)換為term+should
{
"match" : {"title" : "java elasticsearch"}
}
ES會自動給我們轉(zhuǎn)換為如下
{
"bool" : {
"should" : [
{"term" : {"title" : "java"}},
{"term" : {"title" : "elasticsearch"}}
]
}
}
（2）operator：and如何轉(zhuǎn)換為term+must
{
"match" : {
"title" : {
"query" : "java elasticsearch",
"operator" : and
}
}
}
{
"bool" : {
"must" : [
{ "term": { "title": "java" }},
{ "term": { "title": "elasticsearch" }}
]
}
}
（3）minimum_should_match如何轉(zhuǎn)換
{
"match" : {
"title" : {
"query" : "java elasticsearch hadoop spark",
"minimum_should_match" : "75%"
}
}
}
{
"bool" : {
"should" : [
{"term" : {"title" : "java"}},
{"term" : {"title" : "elasticsearch"}},
{"term" : {"title" : "hadoop"}},
{"term" : {"title" : "spark"}}
],
"minimum_should_match" : 3
}
}
