how to change the result list description in the search view

Hello,

As i got a request that I have to change all the text which called "complaints" in the UI frame to "service requests", I am nearly finished but still one point left, In the search view, for example, if you do not enter any criteria and click search, you will get a title or description so called " Result List: More than 100 Complaints Found", how to change the word here to "Result List: More than 100 service request Found"???

Will highly appriecated if someone can give me some info how to change this. Many thanks!
