when you define a search function on a computed field, it is executed as part of the domain filter before any other filters are applied. Therefore, you cannot directly access the results of other filters in the _search function.

However, there is a workaround that you can use to achieve your desired result. You can create a new field on the model, which will store the result of the date filter. Then, you can use this field in your _search function to perform your additional filtering.
Here an example to illustrate this approach:

from odoo import fields, models

class MyModel(models.Model):
_name = 'my.model'

date_filter = fields.Date(string='Date Filter')
computed_field = fields.Integer(compute='_compute_field', search='_search_field')

def _compute_field(self):
# Compute the value of the field based on your logic
pass

def _search_field(self, operator, value):
# Retrieve the filtered records based on the date filter
filtered_records = self.search([('date_field', operator, value)])
 
# Apply additional filtering based on your logic
filtered_records = filtered_records.filtered(lambda record: record.field_name and logic)
 
return [('id', 'in', filtered_records.ids)]

In this example, I've added a new field called date_filter to the model. This field represents the date filter that you mentioned. The computed field computed_field is computed based on your logic, and the search function _search_field first filters the records based on the date_filter field and then applies your additional filtering.

Hi

When defining a search function on a computed field, the search function is executed before any other filters specified.This means that the computed field's search function cannot directly access the result of other filters applied.
To achieve this use domain filter, you can restrict the search to only consider the records that match the existing filters applied.
domain = args or [ ]elems = self.env[modelname].search(domain)

Hope it helps
