My user should be able to use the search box to search by some attribute (numeric) it works.
But I’d like to my customer to be able to search using separator.
Example:
search by : 12345678 = works great
search by : 12-34-56-78 = doesn’t work
Which will the best way to override magento search to parse/rewrite/modify this behavior?
Thank you
If you actually want to override the default search (OOP override, that is) Refer to my earlier answer.
Otherwise @Anton’s answer may be enough for you to use the default search which is always preferable.
