Elasticsearch doesn't index all the text

I am stumped. I reset and index without any error. But when I search it cannot find some of the files with the keywords I deliberately inserted. If there are 5 files with word “xyz123”, only, say 2 of them are found.

The only warning in elasticserach is “The length of text to be analyzed for highlighting [78089] exceeded the allowed maximum of [10000] set for the next major Elastic version.”

I would appreciate any hint.

There is a known issue where the first word of a new line in a document is not indexed

Oh. Thank you for clarification.

@Cult what is the issue ??

still investigating
