Hi Remy, could you paste the analyzer part of the field merchant_name_t please ?
And when you say "it should return more than that", could you explain why with examples ? If I'm not wrong, the field collapsing function is based on indexed values, so if your analyzer is complex (not "string"), "Rémy Loubradou" can be indexed as "remy" and "loubradou". And "Rémy NotLoubradou" could be grouped with "Rémy Loubradou". This could explain the behavior.
