How to Find two words in the middle of the SUBJECT?

[dm_nbhelp]

I need to search for messages with two or three workds that will appear together, but in any position in a subject like.

Example:

The Dog is Big

and I need to find 'Dog is'

What is the correct REGX for this?

Thanks

Did you try 'dog is'? You don't need a complicated regex, that one will work all by itself.
