Full-text Search - Thesaurus relationships
Hi,
The documentation[1]https://www.postgresql.org/docs/current/static/textsearch-dictionaries.html#TEXTSEARCH-THESAURUS -- nicolas says thesaurus can include informations of terms
relationships such broader terms, preferred terms ...
I haven't been able to find out how to exploit those relationship in
postgres. Is there any keyword to and associated syntax to make use of
them ?
Thanks,

No, it should happen automatically.
Essentially, it is an extended synonym dictionary, and if you specify it
for a certain token type in your text search configuration, it will replace
certain phrases with something else.

If "broader than" or "narrower than" have the same behavior than "is
equivalent to" I cannot figure out what's the purpose of them.

Can you come up with a clear question?

Actually no because I finally understood the behavior.
