Regex 正则表达式在指定距离内匹配具有指定单词的句子

如何将一个句子与距离为2个或小于2个单词的培根和肉匹配

Bacon is thinly sliced lean pork meat ----Reject

Bacon is pork meat    ----Match

我试过：

^(\bBacon\b)(\040){1,2}(\bmeat\b)$   => i try to match with the "space" between but it's not working
^(?=.*?\bBacon\b)(?=.*?\bmeat\b).*$  => this will match everything in between regardless the distance

请尝试以下正则表达式：

^Bacon(\s\w+)?(\s\w+)?\smeat$

你可以现场观看

Bacon is thinly sliced lean pork meat
Bacon is meat
Bacon is pork meat
Bacon meat
Bacon is not a meat

Bacon is thinly sliced lean pork meat
Bacon is meat

它发现：

Bacon is meat
