When dealing with large number of transactions, keeping a track of every information is not possible. One way to retrieve an accounting voucher out of large volume of transactions is by searching for a particular word in the narration entered for that accounting voucher.   

Let's take a quick look on how a particular narration can be searched on Tally.  

We would like to add here that if your Tally is integrated with Finsights,biz  you  can easily search for Narrations and retrieve any information from any device any where.
