Thanks Steve. I will try that -- although my impression is that the Stata implementation of -soundex- is based on English, right? Not sure about French keywords (my data in this particular case).

Although I don't have any experience in using it, I would think that this situation may call for -soundex-, check -help string functions- for details.

I could write manual multiple -replace-'s to harmonize keywords, but given the size of the dataset and the variety of keywords, that is hardly feasible. I am aware of the -reclink- user-written command for fuzzy merging but that is for merging two datasets, not for collapsing observations within a dataset. It is not immediately evident to me how I could use -reclink- to solve my problem, but maybe that is feasible?
