Where clause with includes not working

[onedumbquestion]

my where clasue with includes isn't working, it's returning all records instead of the expected filter
@items=Item.includessales).where("unit_price is not null and item_type_id=? and title like ?, @item_type_id, params[:search] and :sales => { :item_id => nil }").ordertitle)

BTW,

@items = Item.includes(:sales)
             .where("unit_price is not null and item_type_id=? and title like ?, @item_type_id, params[:search] and :sales => { :item_id => nil }")
             .order(:title)

I think it's the way I'm rendering my partial I'm causing the index action to run instead of display the results of the search action through the _items.html.erb partial
