Filter_rule search with custom field response

[Deiviya_Sivacoumar]

Hi Team,
I am trying to search email in all existing contacts but in response, it is showing only the basic details of contact, I need all other custom fields as well.
tried &include=contact nothing gives the result. Kindly help.
Attaching sample code below

Post api: https://xx/crm/sales/api/filtered_search/contact?per_page=100&page=1

{
    "filter_rule": [
        {
            "attribute": "contact_email.email",
            "operator": "is_in",
            "value": "xx@gmail.co"
        }
    ]
}

Actual result:

{
    "contacts": [
        {
            "partial": true,
            "id": 125000135502,
            "job_title": null,
            "lead_score": 29,
            "email": "deivi@gmail.co",
            "emails": [
                {
                    "id": 125590,
                    "is_primary": true,
                    "label": null,
                    "_destroy": false
                }
            ],
            "work_number": "23332232332",
            "mobile_number": null,
            "open_deals_amount": null,

        }
    ],
    "meta": {
