如何使用Golang正则表达式查找完全匹配的单词？

Question

I am trying to find words in a large text file. The MatchString method doesn't inherently look for exact word match, rather it looks for the pattern as it should.

How does one check for exact word match using regexp package in Golang? I have tried some regex'es i found on SO, but it didn't work.

Answer 1

Use the zero-length word boundry sequence \b: https://play.golang.org/p/-f0KEKb2EbF

regexp.MatchString("\\bword\\b", test)
