Hi, The documents might be too long to highlight, I think. See "hl.maxAnalyzedChars" in reference guide. https://lucene.apache.org/solr/guide/7_4/highlighting.html
Try to increase hl.maxAnalyzedChars value or to use hl.alternateField, hl.maxAlternateFieldLength to create snippets even if Solr failed to create snippets.
