Subject: Re: newbie question (for John Griffin) - fixed

Hi John,

Please ignore my earlier questions on this subject, as I have got to the 
bottom of it.
I was not passing each word in the phrase as a separate Term to the 
query; 

==I'm not sure I understand. You want a phrase query so they should be
==passed as a phrase in quotes.


instead I was passing the whole string (doh!).

Thanks.

- Chris
