Chris M. Hostetter commented on SOLR-16885:
-------------------------------------------
Root cause is [Lucene issue #
12431|https://github.com/apache/lucene/issues/12431] which changed some default
behavior from the {{UnifiedHighlighter}} Starting in 9.0
There is not likely a fix in Solr.
(I created this ticket mainly for tracking purposes and to assist Solr users in
searching for this type of problem and how to fix if via schema changes)

> This problem can happen when the field has {{termVectors="true"
> termOffsets="true" }} but does *NOT* have {{termPositions="true"}}
> Workaround is to update these fieldtypes to include {{termPositions="true"}}
> and re-index all data.
