Code search API filter query is incorrect

Issue Summary

• The filter query that is described in the API documentation is out-of-date and produces no results - specifically when attempting to search an individual repository for a specific phrase:

Steps to Reproduce

1. Attempt to search an individual repository for a specific phrase using the suggested filter:

   search_query=foo+repo:demo
   

2. Execute the command and note that the results do not display properly vs. when you would perform a similar query in the UI

Expected Results

• The query described in the documentation is correct and can be used without any modification

Actual Results

• The query described in the documentation is incorrect and must be modified to yield results

Workaround

• By performing the code search in the UI, analysing the HTTP request made to the API reveals what query is actually required
• Below is the actual query vs the incorrect query displayed in the API documentation:

  // API Documentation (incorrect):
  search_query=foo+repo:demo
  // Actual API Request (correct):
  search_query=repository:demo foo
  

• With URL encoding, the URL should read as follows:

  search_query=repository%3Ademo%20foo
