Hi,
With Oracle Text, the definition of the ABOUT operator:
"Use the ABOUT operator in English or French to query on a concept. The query string is usually a concept or theme that represents the idea to be searched on. Oracle Text returns the documents that contain the theme."
The two queries below return the same result (doc column is BLOB):
select
score(1) score,
id,
name
from
my_docs
where
contains(doc, 'RMAN', 1) > 0
order by
score(1) desc;
select
score(1) score,
id,
name
from
my_docs
where
contains(doc, 'about(RMAN)', 1) > 0
order by
score(1) desc;
Can someone explain me what is the use aof ABOUT? and what means "to query on a concept"?
Kind Regards
