Description
To fix bug where executing a case-insensitive wildcard query combined with aggregations causes an ArrayIndexOutOfBoundsException. The root cause is related to how Lucene’s automaton handles case-insensitive wildcards without determinizing the automaton, leading to instability during query execution.
This PR fixes the issue by explicitly determinizing the automaton generated for case-insensitive wildcard queries before passing it to Lucene’s query execution layer. By converting the automaton to a deterministic finite automaton (DFA), we prevent the exception and ensure stable query execution.
