### Description This test failure reproduces every time. What seems to happen is that we search with a filter that retains > 50% of documents yet we hit an unlucky condition where the graph is not fully connected and every candidate node we visit gets filtered, so we end up with 0 results. It's kind of a degenerate case that is pretty unlikely to arise in a real graph, yet it seems we ought to have some kind of fallback to exact search for this case. ./gradlew :lucene:core:test --tests "org.apache.lucene.search.TestKnnVectorQuery.testFilterWithSameScore" -Ptests.jvms=1 -Ptests.jvmargs=-XX:TieredStopAtLevel=1 -Ptests.seed=C5E04AD69C13E006 -Ptests.gui=true -Ptests.file.encoding=ISO-8859-1 ### Version and environment details _No response_ -- This is an automated message from the Apache Git Service.
