RuSearchBlock is a straightforward Chrome extension designed to eliminate Russian-language content from Google search results. This open-source plugin automatically appends a specific character to each search query, ensuring that pages containing Russian words are excluded from the results. It is particularly useful for users who continue to encounter Russian websites despite adjusting their settings or IP addresses.

The operation of RuSearchBlock is simple yet effective. By automatically inserting a minus sign followed by the character 'и' into every Google search, it enhances the filtering process. Additionally, it discreetly hides this character in the search bar and the page title, allowing for a clean search history. This makes RuSearchBlock a convenient solution for those seeking a tailored search experience free from unwanted Russian-language content.
