I extended the original "Rename objects..." tool with search and replace function. I hope you find it as useful as me :)
Installation:
1. Exit 3ds Max.
2. Copy .mcr file to <3dsmax_path>\MacroScripts folder
3. Copy .res file to <3dsmax_path>\en-US\MacroScripts folder (or in any other language directory depend on the language you use)
4. Start 3ds Max.
