SharePoint 2013: My Site content is not being crawled

Problem

You have deployed a new Search Service Application and launched a full crawl of all content among all sites, including your farm My Site instance.  On reviewing the crawl log, you see the following warning associated with My Site crawl:

This item and all items under it will not be crawled because the owner has set the NoCrawl flag to prevent it from being searchable.

You're not sure where this setting is.

Solution

1. In any browser, navigate to the root My Site URL.
2. From the Settings gear icon (top right corner), click Site Settings.  The Site Settings page is displayed.
3. In the Search group, look for Search and offline availability.
4. Click this link.  The Search and Offline Availability page is displayed.
   
5. For the Indexing Site Content setting, select Yes.
6. Click OK.
7. Start a new crawl.
