ElasticSearch: TooManyClauses exception when adding highlight - lucene

Question

My query_string query gives me a TooManyClauses exception. However, in my case I don't think that the exception is thrown due to the usual reason. Instead, it seems to be related to highlighting, because when I remove the highlight from the query, it works. This is my original query:
{
"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" : { }
}
}
}
and it gives me the TooManyClauses error:
{
"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
}
This is the query without the highlight, which works:
{
"query" : {
"query_string" : {
"query" : "aluminium potassium +DOS_UUID:*",
"default_field" : "fileTextContent.fileTextContentAnalyzed"
}
},
"fields" : [ "attachmentType", "DOS_UUID", "ATT_UUID", "DOCUMENT_REFERENCE", "filename", "isCSR", "mime" ]
}
UPDATE 1:
This is the stacktrace from the ElasticSearch log file:

UPDATE 2:
This is my mapping:
{
"markosindex": {
"mappings": {
"markostype": {
"_id": {
"path": "DOCUMENT_REFERENCE"
},
"properties": {
"ATT_UUID": {
"type": "string",
"index": "not_analyzed"
},
"DOCUMENT_REFERENCE": {
"type": "string",
"index": "not_analyzed"
},
"DOS_UUID": {
"type": "string",
"index": "not_analyzed"
},
"attachmentType": {
"type": "string",
"index": "not_analyzed"
},
"fileTextContent": {
"type": "string",
"index": "no",
"fields": {
"fileTextContentAnalyzed": {
"type": "string"
}
}
},
"filename": {
"type": "string",
"index": "not_analyzed"
},
"isCSR": {
"type": "boolean"
},
"mime": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
}
Any idea? Thanks!
