SharePoint 2013: How to add people search result in to different verticals

Everything Verticals does not show the people result.
Reason System have different result source for different verticals or Navigation.We can define or add multiple result source data under one verticals.
- Everything (Vertical) have default Result Source: i.e. Local SharePoint Results
- People (Vertical)  have default Result source: i.e. Local People Results

Using Query Rule we can add People result into Everything

Steps are as follows:-

Step1:-

Search Center -> Site settings -> Site Collection Administration -> Search Query Rules:

Step2:

 Select Local SharePoint Results (System) in the Context drop-down:

Step3:-

Once that is selected, click on New Query Rule:

 Step4:-

On the Add Query Rule page, add a rule name, remove the condition, and then click on the Add Result Block link:

On the Add Result Block page change the Title to state "People Results". In the Select this Source, select Local People Results (System) and select the amount of items. The default is 2 and that's probably not enough (just like beer or martinis). 3 or 5 seem like good numbers.

Under the Settings section, as shown above, select the "More" link option and enter "peopleresults.aspx?k={subjectTerms}". Select People Item from the Item Display Template. Click OK.

Back on the Add Query Rule page, click Save.

Run your search again (it may take a moment for the changes to appear):

Happy Coding !!
