Summary by CodeRabbit

• User Experience
  • Added a status message indicating that popular packages are being fetched from Ballerina Central before displaying query results.
  • The message includes the search query and registry name for clearer feedback during requests.

Should we use ballerina/log. I am not sure it is good to have mix of io and log.

[TharmiganK]

From connector team, we follow and recommend the convention to use io prints in main function examples and log statements for service examples.
