This article addresses a common challenge in regular expressions: matching specific word lists fails when target words appear adjacent to each other. By analyzing the limitations of the original pattern (?:$|^| )(one|common|word|or|another)(?:$|^| ), we delve into the workings of non-capturing groups and their impact on matching results. The focus is on an optimized solution using zero-width assertions (positive lookahead and lookbehind), presenting the improved pattern (?:^|(?<= ))(one|common|word|or|another)(?:(?= )|$). We also compare this with the simpler but less precise word boundary \b approach. Through detailed code examples and step-by-step explanations, this paper provides practical guidance for developers to choose appropriate matching strategies in various scenarios.
