dimensional codes » dimensional coded, dimensional models, dimensional model
collision based » collocation based, collision system, collision cables
codes linear » odes linear, models linear, modules linear

• Performing a fuzzy search may retrieve terms with similar spellings: communication ((collision based) or (cognition problem)) dimensional codes linear~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication ((collision based) OR (cognition problem)) dimensional codes linear.
• Adding a wildcard symbol may retrieve word variants: communication ((collision based) or (cognition problem)) dimensional codes linear*.
