+# This file implements regression tests for SQLite library.  The
+# focus of this file is testing OR expressions where terms can be
+# factored from either side of the OR and combined into a single new
+# AND term that is beneficial to the search.  Examples:
+#
+#      (x>A OR x=A)              -->    ... AND (x>=A)
+#      (x>A OR (x=A AND y>=B)    -->    ... AND (x>=A)
