[core] Fix unsupported predicate fallback for global indexes - #8790
Merged
Conversation
Global index readers inherited range and IS NAN visitor defaults that can throw when an index does not support those predicates. Return unsupported results conservatively, preserve wrapper and constant reader behavior, and add regression coverage. Signed-off-by: QuakeWang <wangfuzheng0814@foxmail.com>
