Perhaps you should try some spelling variations:
8.4 models » 5.4 models, 1.4 models, 4.4 models
2.4 models » 14 models
24 modern » 4 modern
14 modern » 4 modern, 7 modern, 8 modern
24 model » 2.4 model, 4 model, 14 model

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22history%((((24 modern) OR (24 model))) OR (((14 modern) OR (((8.4 models) OR (2.4 models))))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22history%((((24 modern) OR (24 model))) or (((14 modern) or (((8.4 models) or (2.4 models))))))%22".
• Adding a wildcard symbol may retrieve word variants: %22history%((((24 modern) OR (24 model))) or (((14 modern) or (((8.4 models) or (2.4 models))))))%22*.
