Hi,

I'd like to compare addresses from 2 different indices using a join function and fuzzymatch. In SQL it would look something like this:

SELECT my.com\_name AS MyName, cust.customer\_name AS CustName,  
my.com\_address AS MyAddress, cust.customer\_address AS CustAdress,  
my.com\_city AS MyCity, cust.customer\_city AS CustCity,  
my.com\_zip AS MyZIP, cust.customer\_zip AS CustZIP  
FROM customer.customers cust JOIN my.customers my  
ON metaphone(my.com\_name, 5) = metaphone(cust.customer\_name, 5)  
AND levenshtein(cust.customer\_name, my.com\_name) \< 5  
AND levenshtein(cust.customer\_zip, my.com\_zip) \< 2;

Is there even a possibility with 2 indices? And if, better as a nested or has\_child/has\_parent query?
