Perhaps you should try some spelling variations:
8.4 modeling » 5.4 modeling, 6.4 modeling, 7.4 modeling
8.4 modern » 8.4 model, 8.4 mode
8.4 models » 2.4 models, 5.4 models, 4.4 models
1.4 models » 14 models, 2.4 models, 5.4 models
14 modern » 7 modern, 8 modern, 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 (14 modern))) OR (((((((8.4 modern) OR (8.4 modeling))) OR (8.4 models))) OR (1.4 models))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22history%((((24 modern) or (14 modern))) or (((((((8.4 modern) OR (8.4 modeling))) or (8.4 models))) or (1.4 models))))%22".
• Adding a wildcard symbol may retrieve word variants: %22history%((((24 modern) or (14 modern))) or (((((((8.4 modern) OR (8.4 modeling))) or (8.4 models))) or (1.4 models))))%22*.
