See full text

A computer receives a formatted query having a plain text word. The computer selects each character in the plain text word. The computer identifies a group of characters from a confusion matrix that are commonly confused with the character selected. The computer generates a set of characters for each character selected, wherein the set of characters begin with one of the each character selected followed by and ending with the group of characters from the confusion matrix. The computer generates a regular expression by concatenating each of the set of characters.
