Question: Every list or doclibrary has this page by default, is it safe to exclude it from crawling? will documents still be crawled if I exclude it?

Answer: 
Check the result sources:

People:

```
{?{searchTerms} ContentClass=urn:content-class:SPSPeople}

```

Local Content:

```
{?{searchTerms} -ContentClass=urn:content-class:SPSPeople}

```

For **local** the minus in front of the content class excludes the people results.
For **people** the contentclass excludes your list.

Create a copy of the people result, add your custom list with a OR to the result source and both should be visible.
My requirement was to mix three types of content types. I created new result source with below query.

```
{?{searchTerms} ContentClass=urn:content-class:SPSPeople} {?OR (({searchTerms}) ContentSource:WCFContacts)} {?OR (({searchTerms}) ContentSource:WCFAccounts)}

```
