*** Please use ezSearch instead of XSLTsearch (it's newer and better) ***
XSLTsearch is the easy, quick, and free search solution for Umbraco web sites. It is fast, completely self-contained, and extremely configurable.
With XSLTsearch you can search for all words and phrases in all document properties and attributes, including your custom properties. Search results are automatically sorted by relevance with search terms highlighted in the results.
Member-protected and hidden content is not returned in search results, ensuring private information remains private.
XSLTsearch installs in all Umbraco sites from v4 through v7.
