I made a search and M2 did gave me search results but definately not the one I am looking for.
I am searching " Drive license " emails where I want to search them & delete some of them I no longer need it from old days.
However , Opera search result did not show me even 1 of the email containing Drive license but something else.
How this could happened and how to correct this ?
Thank you very much.
Most probably the text index database is broken. It's not difficult to make Opera rebuild it but I don't remember now how to do it.
