What is cleaned in MS Search ?

[mpw101 0]

Application tab>Windows>MS Search

What does this clean?  I know it says MS search but I am not sure what that is or where to find it.  For example, is that the search function I am using when I search for a file in Windows Explorer?  Is it the search used when I use the search box in the task bar?

If I tick the box next to it will it mess up indexing and Windows will have to index again?  I have used Ccleaner for years and never ticked the box because I thought it would corrupt Indexing but maybe it just removes the list of searchs I have done somewhere in Windows.

Thank you in advance for information.

Haven't got a clue, and this sort of information is kept close to the developers chests.

Try right clicking on it and picking analyze from the context menu to see if it finds anything on your machine.
It doesn't find anything on mine currently, but I don't use search much anyway.

(It take a guess at: "C:\ProgramData\Microsoft\Search\Data\Temp\" but that is a guess).

If you /export it it doesn't show? Is it a special key?  Can't check myself at this time as i'm away from my PC.

It cleans .log files located in this path:

%CommonAppData%\Microsoft\Search|*.log|RECURSE

 

Which is the same path as (on Win10):

C:\ProgramData\Microsoft\Search
