Hi Aswathy,

With the search option you'll search for records within a table. For example to get out all contacts which are not archived:

# partner_ids will only give back all res.partner records that are not archived (so active)
active_partner_ids = self.env['res.partner'].search([('active', '=', True)])

The filter method is to filter out specific records from a recordset. For example: you did a search for all partners that are active but now you want to filter out those records and only get out the customers:

customer_ids = active_partner_ids.filtered(lambda partner: partner.customer == True)

The filtered option is even documented in the official docs at https://www\\\\\.odoo\\\\\.com/documentation/12\\\\\.0/reference/orm\\\\\.html\\\\\#odoo\\\\\.models\\\\\.Model\\\\\.filtered\\\\\ \\\\\-\\\\\ in\\\\\ general\\\\\ the\\\\\ whole\\\\\ documentation\\\\\ about\\\\\ the\\\\\ ORM\\\\\ is\\\\\ a\\\\\ great\\\\\ topic\\\\\ to\\\\\ read\\\\\.\\\\\ See https://www.odoo.com/documentation/12.0/reference/orm.html#recordsets 
In general you usually use a .search for doing database queries and getting specific results from the database. You'll use filtered() mostly when you want to filter out a part of a recordset in the Python code without doing database operations anymore.
