I tried both Standard and DisMax query parsers and the issue is easily
reproducible. And forgot to mention earlier, I am trying this on Solr 8.6.3
Just to add more clarity this is what I am doing:
I have say a field called File_Content_Field with the following values
indexed and stored: "runnings, running, run, runs"
My query is something like this:
q=File_Content_Field:runnings~0&hl.fl=File_Content_Field&hl=on
With original highlighter, I see the following response:
"highlighting": {"document_id": {"File_Content_Field": ["\n \nTest Dataset
1 Running and <em>Runnings</em> and Runs and R\n \n "]
With unified highlighter, no highlighting is returned:
q=File_Content_Field:runnings~0&hl.fl=File_Content_Field&hl=on&hl.method=unified
"highlighting": {"document_id": {"File_Content_Field": []}
However, runnings~1 works as expected (highlights both running and runnings)
q=File_Content_Field:runnings~0&hl.fl=File_Content_Field&hl=on&hl.method=unified
"highlighting": {
"document_id": {"File_Content_Field": [ "\n \nTest Dataset 1
<em>Running</em> and <em>Runnings</em> and Runs and R\n \n ]
}
