By hitting the return key after a search term has been entered, or by clicking the bottom search link in the drop down results, this will open a drop down of advanced search results for your term:
From here, you can then apply a range of sub-filters via the options on the right hand side, including 'by type', 'by colleague' and 'by time'. These filters help you quickly uncover the most relevant results from your search.
On the right hand side, Idea Drop also shows you related searches where appropriate and on the top of the centre column, you'll see suggested searches with the words 'did you mean?', if we think there might be better terms.
These options are similar in design, functionality and feel to the main filters in your home feed.
