In a word, “no”. The string type is intentionally primitive, no analysis/case
changing is done at all.
You say “you cannot reindex the data”. Why not? Just due to time constraints or
is the original data no longer available?
If all the fields are stored, you can pull the docs from the collection and
index it into a new collection. See:
https://lucene.apache.org/solr/guide/8_1/collections-api.html, the
REINDEXCOLLECTION command.
