How should I use the green search bar on the homepage?
When using the green search bar on the homepage, you can type in the name of the person you are looking for and if they are registered with the Network their profile will come up in the results page with the appropriate filters ticked on the left hand side.
If your search request yields no results, you will not see any filters on the results page -- this is something we are currently working on. In the meantime, if you empty the search bar (while still staying on the results page), you will be able to see the filters on the left.
This also means that you can commence your search with ticking the desired filters by typing something in the search bar on the homepage and then emptying it when taken to the results page in order to apply the filters.
I hope that helps!
