There are several ways to find what you're looking for:
Until now, the system would only treat combinations of words, spaces and hyphens specifically. For example, 'sans serif font' will not return 'sans' or 'sans-serif' but only items that have 'sans serif font' typed exactly.
Now, adding a plus sign will return multiple single keywords, while adding a comma will match either keyword. For instance, 'sans+geometric' will look for items containing both of those words individually--a smaller, more focused result--while 'sans,geometric' will return all items that contain either of those keywords--a much larger result.
Save money! To find out what's currently on sale, simply type, 'sale+' the item. For instance, 'sale+serif' will find all serif items that are on sale.
See what's popular! Use the 'View Popular Keywords' feature in the toolbar to find a quick list of popular items (based on keyword counts).
