Hi,
I am trying to create a ts_vector from a French text. Here are the
operations that seem logical to perform in that order:
1. remove stopwords
2. use hunspell to find words roots
3. unaccent
I first tried:
CREATE TEXT SEARCH CONFIGURATION fr_conf (copy='simple');
ALTER TEXT SEARCH CONFIGURATION fr_conf
ALTER MAPPING FOR asciiword, asciihword, hword_asciipart,
word, hword, hword_part
WITH unaccent, french_hunspell;
select * from to_tsvector('fr_conf', E'Pour découvrir et rencontrer
l\'aventure.');
-- 'aventure':5 'aventurer':5 'rencontrer':3
But the verb "découvrir" is missing :(
If I try with french_hunspell only, I get it, but with the accent:
select * from to_tsvector('french_hunspell', E'Pour découvrir et rencontrer
l\'aventure.');
-- 'aventure':6 'aventurer':6 'découvrir':2 'rencontrer':4
I also tried:
CREATE TEXT SEARCH CONFIGURATION fr_conf2 (copy='simple');
ALTER TEXT SEARCH CONFIGURATION fr_conf2
ALTER MAPPING FOR asciiword, asciihword, hword_asciipart,
word, hword, hword_part
WITH french_hunspell, unaccent;
select * from to_tsvector('fr_conf2', E'Pour découvrir et rencontrer
l\'aventure.');
-- 'aventure':5 'aventurer':5 'rencontrer':3
But I guess unaccent is never called.
I believe this is because french_hunspell is not a filtering dictionary,
but I might be wrong. So is there a way to get this result from any FTS
configuration (existing or :
-- 'aventure':6 'aventurer':6 'decouvrir':2 'rencontrer':4
Thanks,
Bertrand
