如何忽略IllegalArgumentException：当使用带有elasticsearch 5.5的suggester时，找不到字段的映射
在elasticsearch 2.4中，运行以下查询时我可以获得0次点击，尽管映射中没有my_field：
http://192.168.99.100:9200/myindex/_search
{
"suggest" : {
"my_field-suggestions" : {
"text" : "na",
"completion" : {
"field" : "my_field"
}
}
}
}
结果：
{
"took": 30,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 1,
"failed": 4,
"failures": [
{
"shard": 1,
"index": "myindex",
"node": "PSP1qvhZRwy-FWMqt-p72A",
"reason": {
"type": "exception",
"reason": "Field [my_field] is not a completion suggest field"
}
}
]
},
"hits": {
"total": 0,
"max_score": null,
"hits": []
},
"suggest": {}
}
然而在elasticsearch 5.5.3中，我收到了一个错误：
{
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "no mapping found for field [my_field]"
}
],
"type": "search_phase_execution_exception",
"reason": "all shards failed",
"phase": "query",
"grouped": true,
"failed_shards": [
{
"shard": 0,
"index": "myindex",
"node": "Y0UrN9N3RCW7vpWiH0tvtw",
"reason": {
"type": "illegal_argument_exception",
"reason": "no mapping found for field [my_field]"
}
}
]
},
"status": 400
}
在Java程序中，如何处理这个异常？
Failed to execute phase [query], all shards failed; shardFailures {[Y0UrN9N3RCW7vpWiH0tvtw][common_customer][0]: RemoteTransportException[[Y0UrN9N][172.18.0.5:9300][indices:data/read/search[phase/query]]]; nested: IllegalArgumentException[no mapping found for field [my_field]]; }{[Y0UrN9N3RCW7vpWiH0tvtw][common_customer][1]: RemoteTransportException[[Y0UrN9N][172.18.0.5:9300][indices:data/read/search[phase/query]]]; nested: IllegalArgumentException[no mapping found for field [my_field]]; }{[Y0UrN9N3RCW7vpWiH0tvtw][common_customer][2]: RemoteTransportException[[Y0UrN9N][172.18.0.5:9300][indices:data/read/search[phase/query]]]; nested: IllegalArgumentException[no mapping found for field [my_field]]; }{[Y0UrN9N3RCW7vpWiH0tvtw][common_customer][3]: RemoteTransportException[[Y0UrN9N][172.18.0.5:9300][indices:data/read/search[phase/query]]]; nested: IllegalArgumentException[no mapping found for field [my_field]]; }{[Y0UrN9N3RCW7vpWiH0tvtw][common_customer][4]: RemoteTransportException[[Y0UrN9N][172.18.0.5:9300][indices:data/read/search[phase/query]]]; nested: IllegalArgumentException[no mapping found for field [my_field]]; }

我在spring boot项目中使用spring-data-elasticsearch。

在弹性搜索中创建索引时，您必须指定键值对数据。密钥应该是您要搜索的字段名称。请在弹性搜索中输入有关数据的更多信息。
ElasticSearch： http://localhost:9200/ {索引} / _所有/ _mapping /
应该返回以下类型的数据。应该提到NAem领域 {＆＃34; INDEXNAME＆＃34; {＆＃34;映射＆＃34; {＆＃34;的typeName＆＃34; {＆＃34;属性＆＃34; {＆＃34;＆＃34 ;: {＆＃34;类型＆＃34;：＆＃34;文本＆＃34;＆＃34;字段＆＃34; {＆＃34;关键字＆＃34; {＆＃34;类型＆＃34;：＆＃ 34;关键字＆＃34;＆＃34; ignore_above＆＃34; 256}}}}}}}}
