Windows 7: "Search" not showing all results!

I regularly clean out my log files by going to Windows Explorer, selecting "computer" and typing "logs" into the search bar. The results have always shown quite a long list of logs.
Lately it does not find very many logs at all such as "Internet logs," WindowsUpdate logs" etc. I cannot understand why it has suddenly stopped displaying these logs.
Would anyone have a solution to this problem?
Thanks and peace!

My guess is that because you have been cleaning them out regularly, less are being stored. Congrats. You have gotten your computer to run more smoothly than most.

Thanks for your response. I have been cleaning them out often, but they have always regenerated themselves in the past. I don't understand how a regular cleaning of the log files would cause them to stop regenerating now.
Peace!

It doesn't really make them stop regenerating. Looking at my previous post I might have worded a couple things incorrectly. They just might not have been generated lately, and the more often you clean them out, the less are going to be there each time you look. I don't think there is anything wrong, but if you still think some are missing, go to Computer, right click C, and click properties. Run Disk Cleanup and you can delete all log and temporary files from there.

Thanks, I am aware of that. I just went there and the temp files are showing "0" and there is no check box available for log files. I use CCleaner to get rid of most stuff, but it doesn't get rid of the majority of the logs which have to be done manually. It's been awhile now since I've been able to clean out the log files that normally show up in "Search" since the vast majority of them are not being found anymore. Or perhaps not being displayed?
Please let me know if you have any further suggestions.
Thanks for your help. Greatly appreciated.
Peace!

Can you actually find log files that haven't been displayed with the search function?

Is it possible you've upgraded to a later version of CCleaner that deletes more log files than you were used to before?

I did update to the latest version of CCleaner the other day, but this problem began even with the previous version. Until recently all "Searches" were perfect while using CCleaner as well.
Thanks for your response. If you have any other suggestions I'd be happy to read them.
Thanks and peace!

Once again, can you actually find log files that haven't been displayed with the search function?

No, I cannot. Any further suggestions?
Thanks for your response. Appreciated.
Peace!
