Tagizmo has two powerful search options; smart search and multi-filtering.
Smart Search – Easily search hundreds of your saved sites to find exactly what you were looking for by: Description / URL / Notes / Tags
Multi-Filtering – When you tag an item with more than one tag, Tagizmo will filter for just those sites.
And you can combine the two! And coming soon: Search cached content.
