Hi @Ashfaq Naina A 

This requirement ( not by custom variable) you can achieve by either

1) Contexual search

Refer: https://www.youtube.com/watch?v=-3EYZincE0s&t=3s

2)  Similarity Detection (Incident) by short description Using Predictive Intelligence.

Explore both and select one for your requirement.
