ReSearch is a Chrome extension developed by Andrei Polkanov that enhances your web page search capabilities by allowing you to use regular expressions. With ReSearch, you can power-up your searches and find specific patterns or words within web pages.

One of the main features of ReSearch is the ability to search for specific words as separated entities. For example, by inputting "\bthe\b" (without quotes) in the search field, you can find all occurrences of the word "the" as a separate word. This is particularly useful when you want to find instances of a specific word without including it as part of another word.

Additionally, ReSearch can also be used as a regular search tool. Simply input your desired search term, such as "the" (without quotes), and ReSearch will find all instances of that word within the web page.

It's important to note that ReSearch utilizes JavaScript Regular Expressions, so it's recommended to review the official documentation provided by Mozilla for more information on how to use regular expressions effectively. Keep in mind that there may be some differences between the JavaScript regex implementation and other popular implementations like Python regex. For example, the "\w+" pattern in JavaScript regex will also match separated digits like "12" or "2022".

ReSearch is a free Chrome extension that falls under the Browsers category, specifically the Add-ons & Tools subcategory. It offers a powerful search functionality for users who want to leverage regular expressions in their web page searches.
