How to show all completions options

[shauryagoel]

I just installed this plugin and sourced it in my .zshrc file (started from a clean .zshrc file). I then created 2 files with the following name- ray and code-rust. On typing the following in terminal- vim r. I only get suggestions for only the ray file. However, after typing vim rs, I get the suggestion for code-rust. How can I setup the plugin such that typing vim r shows both of the files?
