- William returns, William, Wm., Will, etc.
- Thomas returns Thomas, Thos, Tom, etc.
But check and make certain before you ASSUME the site works that way. And if the site does perform nickname searches remember that they typically are manually programmed in--so your "weird" nickname for Thomas, might not show up.
Experiment if you are uncertain and remember that NOT ALL sites are constructed to automatically perform these nickname and diminutive searches.
