I want to create my own regex to get substring from some logs. This is my script:

```auto
if (doc['message.keyword'].length == 0) { 
    return "unavailable";
} else {
def m = /.*?http(.*?)wsdl.*?\n/.matcher(doc['message.keyword'].value);
if ( m.matches() ) {
   return m.group(1);
} else {
   return "no match";
}
}

```

And my result:  
match case:

```auto
callId = 12345678 RESPONSE Exception :http://10.20.100.30:8000/BOC2Services/boc2/SalePointsRouteService?wsdl detail: java.net.NoRouteToHostException: No route to host

```

no match:

```auto
1600657611591|sendRequest_http10.20.30.1448090BO||wsdlUrl:http://10.20.30.144:8090/BOC2Services/boc2/LocationStaffSaleHistoryService?wsdl: requestContent: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://service.boc2.bccs.viettel.com/">

```

I used to try to use `/.*?http(.*?)wsdl.*?/` instead. But it even no match in two case. I tried in notpad++ and it run well.  
Can you give me some idea about that?. Thanks
