Search result is empty in few subsites

Question

Hi,
Search is giving empty results for the few sub sites. Even though we have run Full Crawl. Last time same thing happened and REINDEX was the solution. 
Could you please advise, what would be the best troubleshooting steps for this situation?
Thanks,

Try Re indexing again and try to wait for the timer job to run for full crawl again...if it still does not appear...Try to open a ticket for the Microsoft support center ...It seems that the timer job might have been stuck at the back end and the back
end team might need to put their hands on to go in and run it manually ! Reindexing this issue
The search index is built up by crawling the content on your SharePoint site. The crawler picks up content and metadata from the documents in the form of crawled properties. To get the content and metadata from the documents into the search index, the crawled
properties must be mapped to managed properties. Only managed properties are kept in the index. This means that users can only search on managed properties.
When you have changed a managed property, or when you have changed the mapping of crawled and managed properties, the site must be re-crawled before your changes will be reflected in the search index. Because your changes are made in the search schema, and
not to the actual site, the crawler will not automatically re-index the site. To make sure that your changes are crawled and fully re-indexed, you must request a re-indexing of the site. The site content will be re-crawled and re-indexed so that you can start
using the managed properties in queries, query rules and display templates.
You can also choose to only re-index a document library or a list. When you have changed a managed property that’s used in a library or list, or changed the mapping of crawled and managed properties, you can specifically request a re-indexing of that library
or list only. All of the content in that library or list is marked as changed, and the content is picked up during the next scheduled crawl and re-indexed
 There are some Service Interruptions currently going on in the few online farms but since you are doing it on the central premise.. It should definitely be working if the backend team is involved or if you check the behavior after re indexing and waiting
for some time ! Give it a try and ill be connected 24 *7 to help u out here...Thanks !
