这个错误是在用elasticsearch查询时使用missing这个api报出的错误:
比如查询语句为:
GET ent_search/_search
{
"_source": ["eid","ent_name","enttype_code"],
"query": {
"constant_score": {
"filter": {
"missing": {
"field": "enttype_code"
}
}
}
}
}
报错为:
{
"error": {
"root_cause": [
{
"type": "parsing_exception",
"reason": "no [query] registered for [missing]",
"line": 6,
"col": 20
}
],
"type": "parsing_exception",
"reason": "no [query] registered for [missing]",
"line": 6,
"col": 20
},
"status": 400
}
这是由于elasticsearch官方去掉了missing这个api,因为exists可以同时满足查询为空和非空两种需求,可参考:elasticsearch 处理null值
