我的query_string查询给了我一个TooManyClauses异常。但是，在我的情况下，我不认为由于the usual reason引发了异常。相反，它似乎与突出显示有关，因为当我从查询中删除突出显示时，它可以工作。这是我原来的疑问：
{
"query" : {
"query_string" : {
"query" : "aluminium potassium +DOS_UUID:*",
"default_field" : "fileTextContent.fileTextContentAnalyzed"
}
},
"fields" : [ "attachmentType", "DOS_UUID", "ATT_UUID", "DOCUMENT_REFERENCE", "filename", "isCSR", "mime" ],
"highlight" : {
"fields" : {
"fileTextContent.fileTextContentAnalyzed" : { }
}
}
}
它给了我TooManyClauses错误：
{
"error": "SearchPhaseExecutionException[Failed to execute phase [query_fetch], all shards failed; shardFailures {[02Z45jhrTCu7bSYy-XSW_g][markosindex][0]: FetchPhaseExecutionException[[markosindex][0]: query[filtered(fileTextContent.fileTextContentAnalyzed:aluminium fileTextContent.fileTextContentAnalyzed:potassium +DOS_UUID:*)->cache(_type:markostype)],from[0],size[10]: Fetch Failed [Failed to highlight field [fileTextContent.fileTextContentAnalyzed]]]; nested: TooManyClauses[maxClauseCount is set to 1024]; }]",
"status": 500
}
这是没有突出显示的查询，有效：
{
"query" : {
"query_string" : {
"query" : "aluminium potassium +DOS_UUID:*",
"default_field" : "fileTextContent.fileTextContentAnalyzed"
}
},
"fields" : [ "attachmentType", "DOS_UUID", "ATT_UUID", "DOCUMENT_REFERENCE", "filename", "isCSR", "mime" ]
}

这是ElasticSearch日志文件中的堆栈跟踪：
