Great for searching documentation

I use this for more accurate documentation search results on my theme shop website. It also lets me limit results to a specific post type (docs) which is handy. Even with improved search relevancy in WordPress 3.7, Relevanssi is still better and necessary for my needs. I also like how it shows me the most popular searches. I check that every now and then to figure out in which areas my documentation is lacking.

I was impressed to see how fas the author was quick to fix a compatibility issue with a new version of WordPress. You get way more than you pay for with this free plugin!
