Add global search to home page

We want to split into sub issues with investigation task for figuring out the sub issues.

• Investigate current product storage implementation.

We want to implement a permananent search button (like trade me) and only search with enter or pressing the button.

We also want the search bar visible on home screen that searches all products.

As a stretch for more issues for people to work on we could also have a dropdown to filter by category and have global search for category screens too.
