Code search with APIv3

Hi. I have been working with APIv3/search and trying to understand how to create a search query without qualifiers. Is it possible ? How can I look up for a specific term across all publicly accessible repositories ?

I am trying the following based on this example I picked from the REST API documentation I could find.

Sample > curl -H “Accept: application/vnd.github.v3+json” https://api.github.com/search/code?q=addClass+in:file+language:js+repo:jquery/jquery

What I need > curl -H “Accept: application/vnd.github.v3+json” https://api.github.com/search/code?q=glyfboost+repo:*

Edit: Just removing the qualifier does not work as well:> q=glyfboost
