It took a few years of kick-starting the Search Everything Plus project and it being subverted by new full-time projects at Sprout Venture before realizing it had to stop. Our goal of fixing WordPress search with SE+ needed too much focus, something we couldn't sacrifice because of growing client projects. After a year of trying and nothing awesome to show we decided to cease all planning and development on the Search Everything Plus plugin/service.
But our goal of fixing WordPress search isn't lost and we have two recomendations for you:
SearchWP They claim it's the best search plugin around and we can't agree more. It's seriously close to what we had planned for SE+, in many ways it's much better than what we counted on accomplishing.
Swiftype Search plugin It replaces the standard WordPress search with a better, more relevant search engine, and in doing so offloads the performance burden of search queries from your database to theirs.
The advantages of both should be clear but if you're undecided we recomend SearchWP becuase of how it doesn't require a subscription.
Sincerely, Dan Cameron Principal and Janitor, Sprout Venture Inc.
