Answer 1

You can use field_get() to change field attribute "selectable", which is used in search_menu.js in web module to decide what fields to show when clicking "Add Custom Filter. Try this:
selectable_fields = ['field1',...]
#api.model
def fields_get(self, allfields=None, attributes=None):
res = super(YourModel, self).fields_get(allfields, attributes=attributes)
not_selectable_fields = set(self._fields.keys()) - set(self.selectable_fields)
for field in not_selectable_fields:
res[field]['selectable'] = False
return res
Related code in search_menu.js:
get_fields: function () {
if (!this._fields_def) {
this._fields_def = data_manager.load_fields(this.searchview.dataset).then(function (data) {
var fields = {
id: { string: 'ID', type: 'id', searchable: true }
};
_.each(data, function(field_def, field_name) {
if (field_def.selectable !== false && field_name !== 'id') {
fields[field_name] = field_def;
}
});
return fields;
});
}
return this._fields_def;
},

Add this filter to your code.
For example: To add filter in Sale Order Line.
<record id="inherit_so_line_filter_view" model="ir.ui.view">
<field name="name">sale.order.list.available</field>
<field name="model">sale.order.line</field>
<field name="inherit_id" ref="sale.view_sales_order_line_filter"/>
<field name="arch" type="xml">
<search>
<filter string="Pending" domain="[('remian_qty','>',0)]" name = "qty_available"/>
<filter string="Lost" domain="[('remian_qty','=',0)]" name = "qty_lost"/>
</search>
</field>
</record>
For example: To add filter using xpath in Sale Order.
<record id="view_sale_order_inherit_search" model="ir.ui.view">
<field name="name">sale.order.search.filter</field>
<field name="model">sale.order</field>
<field name="inherit_id" ref="sale.sale_order_view_search_inherit_quotation"/>
<field name="arch" type="xml">
<xpath expr="//search" position="inside">
<filter string="Total < 1000" name="total_under_1000" domain="[('amount_total', '<', 1000)]"/>
<filter string="Total >= 1000" name="total_above_1000" domain="[('amount_total', '>=', 1000)]"/>
</xpath>
</field>
</record>

Inherit the existing filter like this:
<record id="any_id_name" model="ir.ui.view">
<field name="name">model.nameinsearchview</field>
<field name="model">model.name</field>
<field name="inherit_id" ref="external_id/>
<field name="arch" type="xml">
<filter name="that_field_name_in_exisiting_filter_view" position="replace">
</filter>
</field>
</record>
that's it. Now this will replace the existing code.
