Search Pancake for list of tokens

So I have basic token search working, trying to figure out how to only search against tokens in PancakeSwap, anyone have an idea?

query TokenSearch($search: String!, $network: Network) {
search(string: $search, network: $network) {
network {
network
}
subject {
__typename
… on Address {
address
annotation
}
… on Currency {
symbol
name
address
tokenId
tokenType
}
… on SmartContract {
address
annotation
contractType
protocol
}
… on TransactionHash {
hash
}
}
}
}
