Issue was not completed by expected milestone. This was due to multiple reasons, including:

• Underestimated difficulty of project
• A lot of time was spent parsing through and trying to understand which files to look at and modify
• The user search and the group search were implemented differently, which caused a lot of initial confusion on what to use as a template
• Testing and coding to try and get user input was delayed due to dependencies between tasks

Issue was completed by Sprint 2.
Functionality matches search criteria, however an amendment was made to the issue. Topics which match the query are printed on the console rather than rendered, due to render method running but not causing any changes on the actual website.
