Re: Empty/non-empty field indexing question
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 -pedja Otis Gospodnetic said the following on 12/8/2004 1:31 AM: Empty fields won't add any value, you can skip them. Documents in an index don't have to be uniform. Each Document could have a different set of fields. Of course, that has some obvious implications for search, but is perfectly fine technically.

Correct. No, there is no point in putting an empty field there. Otis --- [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Hi Otis What kind of implications does that produce on the search?
