We read that in Solr 7, Trie* fields are deprecated, so we decided to change all of our Trie* fields to *pointtype Fields.
Our unique key field type is long, and we changed our long field type something like below; <fieldType name="long" class="solr.LongPointField" positionIncrementGap="0" indexed="false"/> We get the error uniqueKey field can not be configured to use a Points based FieldType. I think it is a bug. If lucene decides to deprecate the Trie* filed type, it should also think of these kinds of errors. What is the solution?
