function - User defined match terms for sting distance calculation in R -

-

there many choices of string distance calculation methods in r in package {stringdist} (https://cran.r-project.org/web/packages/stringdist/stringdist.pdf), curious if possible include user defined match items using regex or other ways in jaro or jaro-winker distance calculations? if not, there other packages provide kind of function?

for example: string "usa starwar corporation" (a), "us starwar corporation" (b), "united states starwar corporation" (c) jaro distances between ((a),(b)),((b),(c)),((a),(c)) respectively 0.01449275, 0.2020202, 0.216513. there way define "usa" matches "us" matches"united states" in calculation , therefore distance 0,0,0?

thanks!
