Arun Kumar commented on SOLR-5426:
----------------------------------
I did investigate this issue and found that it is a desired behavior of the
highlighter. The default chars to analyze for highlighter is hard coded and set
to 51200 chars max.
DEFAULT_MAX_CHARS_TO_ANALYZE = 50*1024;
But the document you indexed has more characters to analyze in one of the field
value that causes this issue. But there is a way to increase this max chars to
analyze by sending an additional query param like this hl.maxAnalyzedChars=52300
So if I fire a query as below then the error is not seen.
http://localhost:8983/solr/global/select?q=aa&indent=true&hl=true&hl.fl=*_stx&hl.simple.pre=%3Cem%3E&hl.simple.post=%3C/em%3E&hl.maxAnalyzedChars=52300
Hope this helps.
