Why the xpath method is not working here?

I am trying to find an element on page using xpath but every time I am getting element not found what’s wrong here kindly suggest

Url - https://multi-verse-js.herokuapp.com/main.html

Xpath Value I am using for query -  xpath: //a[@class='active'][text()='Web-Search']

Element name I am searching - Web-search

>Solution :

You can use partial linkText

partial Linktext: Web-Search 
xPath = //a[contains(text(), 'Web-Search')]
