在ES中，执行match搜索的时候，ES底层通常都会对搜索条件进行底层转换，来实现最终的搜索结果。如：
GET /student/java/_search
{
"query": {
"match": {
"remark": "java developer"
}
}
}
转换后是：
GET student/java/_search
{
"query": {
"bool": {
"should": [
{
"term": {
"remark": "java"
}
},
{
"term": {
"remark": {
"value": "developer"
}
}
}
]
}
}
}
GET /student/java/_search
{
"query": {
"match": {
"remark": {
"query": "java developer",
"operator": "and"
}
}
}
}
转换后是：
GET student/java/_search
{
"query": {
"bool": {
"must": [
{
"term": {
"remark": "java"
}
},
{
"term": {
"remark": {
"value": "developer"
}
}
}
]
}
}
}
GET student/java/_search
{
"query": {
"match": {
"remark": {
"query": "java architect assistant",
"minimum_should_match": "68%"
}
}
}
}
转换后为：
GET student/java/_search
{
"query": {
"bool": {
"should": [
{
"term": {
"remark": "java"
}
},
{
"term": {
"remark": "architect"
}
},
{
"term": {
"remark": "assistant"
}
}
],
"minimum_should_match": 2
}
}
}
建议，如果不怕麻烦，尽量使用转换后的语法执行搜索，效率更高。
如果开发周期短，工作量大，使用简化的写法。
