I would like to get pending transactions with using geth.
And I tried to use 'web3.eth.pendingTransactions' on geth console.
So the geth returned ''.
> web3.eth.pendingTransactions 
But I visited Etherscan's pending transactions page.
They could display pending transactions.
It was displayed 'A total of 74,945 pending transactions found' and the transactions list.
Why can they gain pending transactions with elapsed time ?
Is this possible with using geth or other client ?
Or is this the software of their own developing ?
I'd like to get pending transactions with using geth via web3.js (or with using other client via other node.js library).
