How to customize the view on Manage apex classes page in Salesforce?

Hi Piyush,

You’d need to create a filter, use the Contains operator and you can either separate your strings by comma in one filter (effectively each comma is an ‘OR’) or you can add up to 10 filters and apply filter logic to separate your filters by OR instead of AND (which is the default filter logic).

Filter logic is explained in detail here:  https://help.salesforce.com/htviewhelpdoc?id=reports_filter.htm&siteLang=en_US
Thanks
