简而言之，当 Elasticsearch 中期望的聚合器与实际发现的聚合器不匹配时，会出现此错误。这通常发生在您尝试使用的聚合与索引中的字段类型不匹配时。要解决此问题，您可以更改索引中的字段类型以匹配期望的聚合器，或者使用与当前索引字段类型匹配的适当聚合。此外，请确保您的 Elasticsearch 版本支持您尝试使用的聚合。
日志上下文 #
日志"Registry miss-match – expected SignificantTermsAggregatorSupplier; found [“的类名是 SignificantTermsAggregatorFactory.java。 我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入背景的人参考：
CardinalityUpperBound cardinality;
Mapmetadata) throws IOException {
AggregatorSupplier aggregatorSupplier = queryShardContext.getValuesSourceRegistry().getAggregator(config;
SignificantTermsAggregationBuilder.NAME);
if (aggregatorSupplier instanceof SignificantTermsAggregatorSupplier == false) {
throw new AggregationExecutionException("Registry miss-match - expected SignificantTermsAggregatorSupplier; found [" +
aggregatorSupplier.getClass().toString() + "]");
}
SignificantTermsAggregatorSupplier sigTermsAggregatorSupplier = (SignificantTermsAggregatorSupplier) aggregatorSupplier; BucketCountThresholds bucketCountThresholds = new BucketCountThresholds(this.bucketCountThresholds);
