This may be very helpful for those who are not familiar with regular expressions, linux, kfind
What kind of regular expression can be used in kfind,
How about a regular expression list that you can select from drop down on a changeable input bar?
It is the same as choosing the file type on the content tab
It would be nice to have another input bar without integrating with the name column
