Regex for searching a inputed sentence but including special characters

Question

So straight to the point. I am currently making a college project that consists on search a JSON file for specific words/sentences according to 2 types of research: Restrict which means case sensitive and Lexical which means case insensitive And return the occurrencies in bold format

Currently i'm using this regex as a search method

regex = new RegExp(inputSearch, "g"); //case sensistive

and

regex = new RegExp(inputSearch, "gi"); //case insensitive

"inputSearch" beeing the variable that contains the sentence/word that0s supposed to be found, my problem is that i need to include special characters such as these ".:,;!?-_" so if, for example, i search for "How are you?" it would return all the occurrencies of that sentence including the "?"

Can anyone please help me?

Thank you in advance

`regex = new RegExp(inputSearch.replace(/(\W)/g, "\\$1"), "gi");` — Avinash Raj, Jul 02 '15 at 10:41
@AvinashRaj awesome , really good solution, I was just wondering how to achieve — Dimag Kharab, Jul 02 '15 at 10:43
If you're looking only for exact words and not using any regex features, then you should rather use `indexOf`. Case insensitivity can be achieved by making both text and word lowercase. — Bergi, Jul 02 '15 at 10:53

Just escape all the special characters present in your variable with string.replace function.

var regex = new RegExp(inputSearch.replace(/(\W)/g, "\\$1"), "gi");
