Fueto is a free, fully-hosted, API-based, outsourced search engine for your WP blog. Fueto wins because we use social signals to rank search results.
Fueto brings socially relevant results to your readers when they search within your WP blog. Fueto replaces the default search with socially-powered results. Out of the relevant matching posts, we bring higher exposure to your most viral posts (most shared, liked, etc).
Give it a shot, your readers will love your blog search powered by Fueto!
