Need help for complex data sort SQL Server

Question

I need help for complex data sort from database. Suppose my data stored in table like this:

Description
--------------
JCB Excavator - ECU P/N: 728/35700
Geo Pri         


        

Answer 1

1. Write a function to tokenize a string into a table of words. eg: How do I split a string so I can access item x?
2. Apply this function to the search string and the description table
3. Join the two results with cross apply; group the results, count and sort.
