I want to get search result for the only Equity from BSE or NSE and not FNO data, but when I try with filter request object. It returns 0 results. Please give me some brief on it.

My request is:

{
“filterRequest”: {
“instrument_token”: “”,
“exchange_token”: “”,
“tradingsymbol”: “”,
“exchange”: “”,
“instrument_type”: “EQ”,
“segment”: “”
},
“searchPatterns”: {
“tradingsymbol”: “SBI”
},
“paginationDetails”: {
“offset”: 0,
“limit”: 100
}
}

and, response I get is:

{
“instruments”: [],
“totalCount”: 0
}
