Wp-spp, or "Wordpress Search Plus Plus", is a C++ project to create an effective search engine for Wordpress. It connects to MySQL database via interface routines provided by MySQL++ and uses boost library to handle keyword searching and highlighting.
Compiled CGI code of wp-spp should be at least an order of magnitude faster than its PHP competitor when using complicated searching logic.
Features include (not a complete list):
- search on both posts and comments
- highlight search results
- compatible with UTF8 encoding
- controllable context length before/after highlighted keywords
- suppress HTML tags in search results
- display posts and comments in a tree structure
- paging
- support various search strategies for multiple keywords
