错误原因翻译：
对于需要每个⽂档字段数据（如聚合和排序）的操作，没有对⽂本字段进⾏优化，因此默认情况下禁⽤这些操作。请改⽤关键字字段。或者，在[interests]上设置fielddata=true，以便通过取消反转索引来加载字段数据。请注意，这可能会占⽤⼤量内存。 执⾏操作：
curl -X PUT "localhost:9200/megacorp/_mapping?pretty" -H 'Content-Type: application/json' -d'
{

"interests": {
"type": "text",
"fielddata": true

}

重新执⾏聚合查询
curl -X GET "localhost:9200/megacorp/employee/_search?pretty" -H 'Content-Type: application/json' -d'
{
"aggs": {
"all_interests": {
"terms": { "field": "interests" }
}
