• Performing a fuzzy search may retrieve terms with similar spellings: (transition or translation) on petri (nets OR net) and other models of concurrency,~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (transition OR translation) on petri (nets OR net) AND other models of concurrency,*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(transition or translation) on petri (nets OR net) and other models of concurrency,*".
