High Memory Usage - all versions

[Ishmael Matthew]

I've been meaning to report this for a while, and I'm finally doing it. I am using Windows 7 x64 and all versions including the latest one seem to have this issue. The more searches I do and the more results obtained, the higher the usage, but it doesn't always happen immediately. Then I have to remember to restart after doing a bunch of searches. I'm currently running Qt 2019.7.22, as it seems to perform better than the latest version.  It seems the issue is when the search tabs are closed, the data is still saved somewhere and the memory used never decreases and stays the same, accumulating with each search resulting in so much memory used. Even if all search tabs are closed, memory usage doesn't drop. I wonder if anyone else has been having this issue and if it's possible for it to be be fixed. Thanks
