[Zope] Question about AdvancedQuery

[julian]

Hi,

I want use a query like :
query['getPresta_chambres'] = { 'query': ["15"], 'range': 'min' }

But with AdvancedQuery I don't see how make it :
---------------------------------------------------------------------
query = And(Eq('portal_type', 'Meubles'))
query = query & Eq('review_state', 'published')

# This query don't run :
query = query & Eq('getPresta_chambres', { 'query': ["15"],'range': 'min' })
---------------------------------------------------------------------

Could you help me :p ?
