Subject Re: Empty/non-empty field indexing question
Date Wed, 08 Dec 2004 14:54:03 GMT
Hi Otis

What kind of implications does that produce on the search?

If I understand correctly that record would not be searched for if the 
field is not there, correct?
But then is there a point putting an empty value in it, if an 
application will never search for empty values?


thanks
