Hi, thank you for the suggestions. However, I think that this is not going to work.
Suppose I have a product with a title='kMix Espresso maker'. If I tokenize this and put the result in product_tokens I should get '[kMix][Espresso][maker]'. If now I try to search with facet.field='product_tokens' and facet.prefix='espresso' I should get only 'espresso' while I want 'kMix Espresso maker'. Is that correct ? Cheers, Ugo.
