Crystal Reports- Filter field by specific word(s)

Hello,

I am not sure if this possible. I have a table memo text field called close description for service incidents. I need a report to only display records where the close description contains the words ( replaced, replace ,swap , UPS, Etc). I dont know how to code this in SQL. And if it can be done are the words case specific?

Any assistance would be greatly aprreciated

Thanks all
