This is the default Twitter Bootstrap template to illustrate the usage of Livesearch.
On this demo page you can use the Live Search with the search forms at the top of each page and with the search form under the Search menue point. Live Search is ideal for smaller and medium sites.
Live search collect all urls from your website and cache them into a special cache directory. The search process will be done over the cached files, so only caching will cost time. More info can be found in the How it works article.
On the search page you can find a Search Cloud at the right column too.
You can search for images and within PDF files too
