I m so sorr thy.. that’s right, I done a mistake in default number setting… Now that’s work !
That query is just a test on a custom toxonomy, but I ll made it only on a big cat.
This site is a bit complexe with almost 80 categories and 40 toxonomies more 30 customs fields… So query something is a bit hard for me 😀
Thanks a lot for your nice support !
