This issue is there to enumerate ergonomy remarks tab by tab.
Maybe sub-issues should be create to correct problems one by one.
All these points are opened to discussion.

General

1. Label "Résultats de recherche" : I would have named it like this "Type de recherche" or "Recherche sur", because on a search we can have contents associated to pages, programs with their subprograms, resources, etc.
2. Label "Formations" : So this label maybe should be "Offre de formation", because it's a search on programs and optionally subprograms, and in the future courses ?
3. The fields "Afficher les parcours" and "Rechercher dans les parcours" are specifics to the ODF et should only visible (or available) when "Formations" is selected in "Résultats de recherche", it also should be in a different tab "Specificités" or at least in a fieldset.
4. Same note for "Type de contenus" which can be used for all searches (I'm not sure for "Documents" and "Pages"), but not for the ODF.

Criteria

1. With the tab name itself, we expect to define the criteria available for the search. But in reality, we both pre-filter the search results and select visitor criteria. It's very disturbing.
2. The checkbox "Afficher le nombre de valeurs pour les critères énumérés" should have its place here if this tab is really used to select criteria, I think his place his better with the facets definition.

Results

1. We only offer the facets in this tab, not the free text fields (like label, keywords or whatever), it's in a different tab, it's a little bit weird to select criteria in two different tabs. Facets and free text fields are both criteria for a "normal" user. Maybe the tab should be named "Configuration" (of criteria and results) or "Critères et résultats" with different fieldsets "Critères", "Tri", "Résultats".

Other

1. The ODF search has no default render.
