Hello,

This module will allow you to get filters in the search view which are done on the same field to be filtered with "and" condition instead of native "or" condition.

Example:

In the native search view of partners, you've got "Customers" and "Suppliers" filters. When you click on both you will get all the customers and all the suppliers displayed.

If you add """ filter_condition="and" """ in the filters like this (once this module installed):

<filter string="Customers" name="customer" domain="[('customer','=',1)]" help="Customer Partners" filter_condition="and"/>
<filter string="Suppliers" name="supplier" domain="[('supplier','=',1)]" help="Supplier Partners" filter_condition="and"/>

When you will click on both, you will have all partners which are both customer and supplier.

You can check out our module hr_recruitment_skills on apps which is making this automatically working it to check all applicants which got all skills needed for a job.

Tell me if that's not clear enough.

Best regards.
