Non Contiguous Terms

Hi,
I try non contiguous selection of itens.
Ex:
Long term support
support long term
I need select this itens with word entry is "Long Support". I change
the regular expression to (?![^&;]+;)(?!<[^<>]*)(long|support)(?!
[^<>]*>)(?![^&;]+;) and highlight work. But if spaces is detected no
itens selected.
You have suggestion?
