-> where title not like '%word%'
If you are suggesting a query such as:
select id from biblio
where title not like '%word%'
intersect
select id from subject
where subject not like '%word%'
intersect
select id from keyword
where keyword not like '%word%'
I don't believe this will work. Let's say you have a title that satisfies
the query, that is it doesn't contain "word" If no child records in the
subject or keyword tables exist, the intersect will elimimate this valid id
from the results.
Or am I not understanding something?
And yes, I can see what you mean already about taking lots of time -- even
for a rather small amount of data!!
