Content Search Web Part shows Subsite that has been renamed

Question

I'm having an issue with the CSWP.  The query that i have set is returning exactly what i want however, i renamed a subsite to a different name and the CSWP is showing two line items in the web part.  1 for the old subsite and 1 for the newly named
site.
I though this would self correct when the search fully crawled but it doesnt appear to fix itself.  It had been about 3 days since i made the name change.
Example CSWP displays subsites: Site1, Site2 and Site3
Site1 was renamed to Site4 and the url has changed.  CSWP is now showing Site1, Site2, Site3 and Site4 instead of Site2, Site3 and Site4
If you click Site1 it goes to a page 404 not found site.
Any suggestions or ideas would be appreciated.

Hi,
I think it is expected that the stale records may exist right after you renamed the site and did a
fully crawl because there are some policies which controls how crawl component deal with non-existing items.
Though those documentations are for SharePoint 2010, it still apply for SharePoint 2013 with different default values.
Managing crawl deletion
policies for SharePoint Server 2010
Manage deletion of index items (SharePoint Server 2010)
SharePoint 2013 Default
ErrorDeleteCountAllowed
10 times
ErrorDeleteIntervalAllowed
240 hours
ErrorCountAllowed
15 times
ErrorIntervalAllowed
360 hours
RecrawlErrorCount
5 times
RecrawlErrorInterval
120 hours
DeleteUnvisitedMethod
1
Therefore, you can either:
Wait for 15 days and the make sure the
ErrorCountAllowed exceeds 15 (15 times crawls happens after you renamed the site). Then the stale item will disappear.
Set a lower value on
ErrorDeleteIntervalAllowed and
ErrorDeleteIntervalAllowed and then set DeleteUnvisitedMethod=0 to fasten the deletion of stale records.

Get current value:
$ssa = Get-SPEnterpriseSearchServiceApplication
$ssa.GetProperty("Property")
set New value:
$ssa = Get-SPEnterpriseSearchServiceApplication
$ssa.SetProperty("Property", NewValue)
