Hi! I was able to reproduce this on current `main` and opened a draft PR with a small fix: https://github.com/apache/lucene/pull/16382 The issue happens because consecutive unescaped `*` wildcards are converted into separate `Automata.makeAnyString()` automata before concatenation. The PR collapses consecutive unescaped `*` tokens while preserving escaped `\*` as a literal. Locally, `WildcardQuery.toAutomaton(new Term("field", "*".repeat(10000)))` went from building `50,005,000` transitions to building `1` transition. I also added a regression test and verified it with `TestWildcardQuery` and `:lucene:core:check`. -- This is an automated message from the Apache Git Service.
