/search/transactions allows the caller to search for transactions that meet certain conditions. Some conditions include matching a transaction hash, containing an operation with a certain status, or containing an operation that affects a certain account. /search/transactions is considered an "indexer" endpoint and Rosetta implementations are not required to complete it to adhere to the Rosetta spec. However, any Rosetta "indexer" MUST support this endpoint.
