Type one Greek word, in whatever form the text shows it, and this finds every place the same word stands, however it is spelled. It searches on its own — it ignores the Greek and English boxes above.
Ask for terms that fall near each other in the verse, in any order (or a fixed one). It searches on its own — it ignores the boxes above.
Ask for a shape alone — case, number, mood — with no word attached. Across a whole work that matches thousands of ordinary forms and is not a result. Scoped to one book it can be: pick a single work and book below, then set the shape to look for. It searches on its own — it ignores the boxes above.
Pick one work and one book above — a grammar search on its own only runs scoped to a single book.
Type Greek in Greek letters or Beta Code (mhnis = μῆνις). Use * for a wildcard: polutrop* matches πολύτροπος, πολύτροπον, etc.
