Regular Expression Boundaries and Special Characters

Question

I have a regex to avoid all special characters in the search bar. This works great, however I cannot get it to work with layers. For example, with haystack

add +

or

add (+)

and needle

+

regular expression /\+/gimatches "+". However, the regular expression /\b\+/gidoes not have. Any ideas on how to make this work?

Using

add (plus)

like a haystack and /\bplus/gias a regular expression, it corresponds to a fine. I just can't understand why runaway characters have problems.

Answer 1

... , a , d, . \b (/\b\+/) +, , .

Answer 2

Answer 3

/\b\s?+/gi

Edit:

, . + :

/\b[^+]*+/gi
