1) Pull up your inventory on www.pathofexile.com and open your stash.
2) Use the provided search field to enter a search term
PoE Stash Searcher++ will then search the opened tab for an item that has a name, mods, or micro-transactions that match your search term. Moving tabs will resubmit the search query after the new tab is loaded.
