Searching a string variable for various words contained in another variable

[ciro]

hi,

I am trying to find possible matches between two dataset by string variables, that contain the name of companies.

I did a full join of the two datasets.

I have experimented with compged but I would like to try another approach: count the words of the variable of the second dataset found in the variable in the first dataset.

for instance say after the join I have something like this

var1                                      var2

AAA BBB corporation          AAA BBB limited

AAA BBB corporation           AAA BBB corp.

AAA BBB corporation          CCC DDD EEE ltd

I would like to compute a variable that has the following values:

var1                                      var2                           score

AAA BBB corporation          AAA BBB limited          2

AAA BBB corporation          AAA BBB corp.            3

AAA BBB corporation          CCC DDD                   0

As you see in the second record,if possible, i would take into account punctuation.

Any help is, as always very appreciated.

thank you very much in advance
