By default, terms are space separated, and logically ANDed.
You can search for cylinder layout with common terms like v6 or i4.
FWD, RWD, AWD and 4WD can search on front wheel drive, rear wheel drive, etc.
Use ~ to remove results with that term. eg: audi ~a4 will return results with audi and not a4.
Group terms with ". This means that the phrase must be present. eg "ferrari f40".
You can OR terms by separating them with a | character. eg lancia beta|gamma will find Lancia Gamma OR Lancia Beta terms.
You can also add keywords to further refine the search based on fuel type (petrol, electric, etc), aspiration (turbo, natural, etc), body type (saloon, hatchback, etc) and engine capacity in either litres or cubic inches (eg 2.0, 427, etc).
