Thank you Shawn for the valuable inputs. I am assuming, please correct me if I am wrong => If we have two fields one has a large amount of text wrt to a field with shorter text like description and title. So, the Number of the tokens created for the description field will be much high w.r.t. the title. So if I search in the title field, it will be comparatively fast w.r.t. to the description field
If the above listed is true then in the case of merged fields, no of tokens have increased exponentially in a single merged field and could be a possible reason?
