i am trying to identify key words from a list of transaction data and have been experimenting with the regex_match function. However, i have come across an issue where the key word is picking up a wildcard of the key word contained in other words
by way of example, the regex match function uses the key word "IGA" (a local supermarket franchise) but is returning additional words that contain "IGA" such as "SPIGA" .
regex_match([vendor], ".*( IGA |Woolworths|Coles|Harris Farm|Aldi|Greenwood Grocer).*")
For example the data set could include
IGA North Sydney
IGA Lane Cove
VIA DIA SPIGA
How can i update this expression (or utilise other tools) to ensure i am only picking up transactions that contain an exact match to the key word? In the above example, i would only want IGA North Sydney, IGA Lane Cove and IGA Burwood to be identified and not "VIA DIA SPIGA"
