Is there a way to control what columns appear in the search window and/or the header descriptions of

This is really 2 questions and if it is in the wrong community please adjust.

1. Is there a way to control what columns appear in the form search?  Example if I did a wild card search for customers in the Sales Order entry header screen.  Is that something we can adjust or is that a customization in which will involve a developer?

2. Is it possible to adjust the header of a column within the form search? If the prompt is adjusted we are looking for the column to be adjusted so they match.  Is that something we can control under CRM administrator?  How can you know what the datasource is if that is the case?
