SEARCH function in spreadsheet

SEARCH function in spreadsheet

How do I search for text in the spreadsheet? Example, we have a job number register. We list the job number (1000) and the customer name (ABC Company). We need to be able to search for job numbers or customers in this spreadsheet. We have hundreds of jobs listed and it would be much faster to be able to find the names with a search. Please let me know asap.

Thanks,
