Why is the dashboard search function so bad?

Is there any way to improve the search function within woocommerce, specifically for searching through users? There doesn’t seem to be any set parameters for showing results. I will for example search ‘mary’ or ‘smith’ and nothing will show even with someone registered with username ‘marysmith’ with their registered name being ‘mary smith’. But someone else eg username ‘tomsmith’ with name ‘tom smith’ will show in the results when I search ‘tom’. It would save a lot of time and frustration if I could just search any term and if that term is anywhere in their account details, they would show in the results. Thanks
