This search engine uses a layered fine-tuning method. Each subsequent row will only search within the results of the row preceeding it. To not use a row, simply leave it blank.
The engine uses the following operators to enhance the search: + prepended to a word makes that word non-optional; - prepended to a word omits that word; * appended (and only appended) to a word is a wildcard; " " around words will force the engine to search for that phrase as it is typed.
The presently existing classifications are landscape, portrait, plants and animals, buildings, artefact, anatomy, design, design (artefact), design (tattoo) and design (scarification).
