How to create Alerts

Hi

This is my search query-source=******* | table ORDERID "Delay(in days)"

This is the result of the search query ORDERID Delay(in days) 1 269150751 4.00 2 269126721 7.00 3 269157489 21.00 4 269153074 114.00 5 269159590 217.00 6 269110381 118.00 7 269163859 24.00

I want to create Alerts for those ORDERIDs whose Delay is greater than 100.

Please tell what type of alert i should select and important parameters
