Content search icon
I am working on a job portal where I want to define icons for find resume(people) and find jobs. For the people, I used the {user-search} icon but for the job, I need a specific icon which is very similar to the user-search icon. 

I request to modify the {file-list-2-line} icon in square format and add a search icon same as {user-search} 

## Icon Request

* Icon name: content search
* Tags of this icon: content search, file search, document search, search
* Screenshots of similar icons:
