2.2.6 - Change default search engine to use 'AND' instead of 'OR'

[gsdan]

For example, if I were to enter the string "Dog Cat", the default search engine would return all Items with either "dog" or "cat" in the SKU (we weight our search more heavily on SKU).

I want to change this so that the only items that are returned are SKU's that match the entire string, so SKU with "dog cat". How can I do this?

Do you only want to do this for SKU or all attributes in the search?

I would think they are all handled similarly? If it makes a difference I'd say all attributes.

Any ideas?
