Sman is "The Searcher for Man Pages", an enhanced version of "apropos" and "man -k". Sman adds several key abilities over its predecessors, including stemming and support for complex boolean text searches such as "(linux and kernel) or (mach and microkernel)". It shows results in a ranked order, optionally with a summary of the manpage with the searched text highlighted. Searches may be applied to the manpage section, title, body, or filename. The complete contents of the man page are indexed. A prebuilt index is used to perform fast searches.
