The search view in Odoo allows you to define default filters to help
users efficiently organize and access records. These filters are
applied using the tag within the search view definition,
based on specific conditions. By configuring default filters
this way, you can streamline the user experience by
automatically applying commonly used filters—removing the need
for users to manually select "Add Custom Filter" each time.
<filter string="Sales Orders" name="Sales" domain="[('state','not in',('draft','cancel','sent'))]"/>
