Dear Statalist,
I have a string variable that contains values something like this:-
"outside the red lion pub"
"red lion"
"in the red lyon"
and so on.
I need to search this variable for names (e.g. "red lion") and would like to
do so in such a way that overcome the inevitable typo (e.g. "red lyon").
How about using Michael Blasnik's implementation of Donald Knuth's
SOUNDEX algorithm:
clear
input str25 var1
"outside the red lion pub"
"red lion"
"red lion"
"redlion"
"in the red lyon"
"blue lion"
"red troll"
end
egen foo = soundex(var1) ,length(12)
gen tag = regexm(foo, "3.*5")
