I'm currently working with a customer where People search isn't returning results like they want. Their primary piece of feedback is that if they misspell a name, it's very unlikely that they'll get a match. They liked the experience in SharePoint 2010, but 2013 is making them less than happy. We did some digging and it turns out that "Fuzzy Name Search" isn't working in their environment. The following shows how to troubleshoot the experience. I MUST THANK Igor Veytskin for his help with this. He provided most of the expertise and the log info you see below.
This functionality gets logged to the ULS logs under the category "Fuzzy Name Search". Crank your ULS logging to VerboseEx for that category by doing the following.
Set-SPLogLevel -TraceSeverity VerboseEx -Identity "Fuzzy Name Search"
Then, execute a few queries. Open your ULS logs. You need to look where your Query and Index components are hosted. You should see something that looks like the following, for a successful query .

BUT, if you don't find what you're looking for, you might see something like the following, indicating fuzzy search isn't working .

To fix this, you likely need to check the permissions on the folder/location listed in the ULS logs. This is what the default permissions look like on the folder. Make sure yours match. Make sure the account you're using for the Host Controller and Search Service exists in the WSS_WPG group. This needs to happen on both the Crawl Component Servers and the Query Processing Servers. If your SharePoint permissions look problematic beyond this location, you can also try to leverage the Initialize-SPResourceSecurity PowerShell command . This will attempt to reapply all the necessary permissions SharePoint requires. It must be done on each server.
Assuming you saw the permission error, once you fix permissions, things should come back to normal. You may need to restart search services, or even the whole server. When that's completed, it will take some time, possibly 24 hours, to do the behind the scenes magic to build the cache. If you see the following entries in your ULS logs, you know things will be working shortly. These are logged with the VerboseEx setting enabled.
CCAPeopleIntentNameSearchProducer : Boot-Strapping of the Fuzzy name searcher is not complete. Reason: Auxillary-CCA datacache for tenant:XYZ is currently being constructed. People Intent search will start working after the cache is completely populated. This is expected.
When you're all done, don't forget to set your ULS logging back to your desired/non-troubleshooting setting.
