> The [doc|https://docs.oracle.com/database/121/DWHSG/pattern.htm#DWHSG8986] has already defined pattern operator {{Concatenation}}. For example, pattern {{A B}} means that events matching pattern {{A}} and {{B}} should occur successively. There are also many use cases which require patterns to match events which not occur successively.
