Stata Substring Search [Data]

To search for a substring in your string variables, the syntax for the conditional is:

if regexm(variable,"search-string")

For example, if you are looking for "ondas" in the auto database:

sysuse auto
l if regexm(make,"ondas")

Note that the string can take regular expressions. I.e., the following returns results where the make starts with "A" or "H"
