searchindexer.exe extermemly high cpu usage - for days

Not certain what to do, I've rebuilt the index, manually deleted the index data folder, completely removed, restarted and then reinstalled Windows Search from the add/remove Windows features, I've also chkdsk /f'd my drives.

When the Searchindexer.exe is using as much CPU as it can I've checked with resource monitor and it isn't reading from or writing to any files, just chewing through CPU cycles.

Edit: more info

I created a dump of the searchindexer.exe and opened it with a debugger tool, this is the contents

I've also deleted my Outlook data files and started from scratch with my emails, and made sure the data folders aren't over a gig.

I've installed all the updates available for Windows 8 and I've also ran sfc /scannow.

I would appreciate if anyone could offer any help at all, thanks.

Hi Joenathan,

 

disable the service in Services, restart the computer and then re-enable the service.
I tried that, I even completely uninstalled the service from the add/remove Windows features, rebooted the PC and re-added it, and same deal.

In any case I've found out what the problem is, it is the korwbrkr.dll, it seems to be related to a Korean dictionary, as if the indexer is trying to index something with Korean characters in it(not aware that I have anything like that), and that is throwing it for a loop. I've renamed the korwbrkr.dll to korwbrkr.bak and it's related dictionary file and deleted the search index and I let the indexer run all night and it is showing that indexing is complete, and I have no more high CPU usage.

I was dealing with high CPU usage from the indexer for weeks, now my system is at peace.
