[rules-users] is there any 'followed by' in Drools as we have in esper

[skatta1986]

Actually I have tried this operator "after", but doesn't work properly as the
events are inserted into working memory one by one within fraction of
seconds. 

Consider EventRecords EventRecord(name=katta, eventType=REQUEST, id=1),
EventRecord(name=katta, eventType=EVENT_UN_AUTHORIZED, id=1) and
EventRecord(name=katta, eventType=REQUEST, id=2)

Drool:
when
    ($eventReq : EventRecord(eventType == "EVENT_REQUEST", respRecv ==
"false") from entry-point "AggStream") 
    and ($sipResp : EventRecord( eventType == "EVENT_UN_AUTHORIZED", name ==
$eventReq.name, id.getCallId()=r1.getId(), respRecv == "false", timeStamp >=
$eventReq.getTimeStamp(), this after[ 0s, 10s ] $eventReq ) from entry-point
"AggStream")
    and ($eventReq2 : EventRecord( eventType == "EVENT_REQUEST", name ==
$eventReq.name, respRecv == "false", timeStamp >= $eventReq.getTimeStamp(),
this after[ 0s, 10s ] $eventReq) from entry-point "AggStream")
    
then
        System.out.println( "++++++ Counter events : unauthorized2 event : "
+ $eventReq.getname()+", $eventReq.getId()="+ $eventReq.getId()+",
$eventReq2.getId()="+ $eventReq2.getId());


This rules give the below output:
++++++ Counter events : unauthorized2 event : katta $sipReq.getId()=1,
$sipReq2.getId()=1

++++++ Counter events : unauthorized2 event : katta $sipReq.getId()=2,
$sipReq2.getId()=2

But Expected output is:

++++++ Counter events : unauthorized2 event : katta $sipReq.getId()=1,
$sipReq2.getId()=2
