I don't know your specific requirements, but not wanting to move
your cursor should not prevent you from using search(). Just save
the cursor position, save the window position, move the cursor to
the start of the search range, and when you're done with the
searching, restore the window position and the cursor position.
I've done this in a number of plugins and I can't even tell that the
cursor ever moved.
