How do I load multiple files that have a certain word in the filename?

So I'm loading multiple files from a folder and I've managed to limit the files to a specific filetype, such as dat files. However, the files have different names and may include words like "uni" or "bi" or "tri" in the title. Is there a way for me to load only files that have that word in the title? This is what I have so far.

directory_name = uigetdir;
files = dir(fullfile(directory_name, '*.dat'));
fileName={files.name};

Have a loop over the files, adding the name to a cell if the name contains the letters you want. You can use strfind() for that.
