**[Twitter's advanced search][1]** does not support such an option, but you can try some 3rd party like: 

* **https://www.favourites.io/**
* **http://www.tweetattackspro.com/**
* **https://ifttt.com/**

You can also use **[Twitter's API console tool][2]** by authenticating through Twitter in the browser and providing your handle and userid.

The last resort would be to use Twitter directly:

* type the name of the user whose favourites you want to see into the top search box. If you want to view your own favourites, click the **Favorites** link on the right side of the screen and jump to the last step
* click the user's name on the right side of the screen under **People results**
* open the **Favorites** tab which will display all tweets the user has made a favourite
* press **<kbd>CTRL</kbd>** + **<kbd>F</kbd>** and type in a keyword to search the favourites on that page (if a match is found, the favourite will be highlighted)
