[Anusha-Padmanabhan]

What would you like to be added?

This functionality enables the explorer to retrieve data using block id, block range (for example, blocks 1 to 10), and transaction data by giving the transaction id .Using these inputs, matching data are pulled in accordance with the user's search selection. First it will check whether the data is available in the PostgreSQL, if it is there it will fetch from there, otherwise it will fetch from blockchain.

Why is this needed?

With this new feature, data is fetched from the blockchain if it is not available in PostgreSQL using the block number, block number range, or transaction id.
