In product template search view is defined a field to do search by product attributes:

<field string="Product Variant" name="product_variant_ids" filter_domain="['|', ('product_variant_ids.name','ilike',self), ('product_variant_ids.attribute_value_ids.name','ilike',self)]"/>

product_variants_ids is a one2many field in product.template. When I write some attribute value, it brings the correct record, but when I write the atrribute name, it brings nothing, for example, in attribute page for some product I have:

MEMORY   32gb

COLOR      red

If I type 32gb, it brings record, whereas if I type MEMORY, brings nothing

Can any one help me? I would also like to understand filter_domain of this example.

Thanks!!
