Knowledge base contains information on how to use Relevanssi. There are lots of features that are documented in the knowledge base. Here's an index to the knowledge base, with all the entries sorted under different topics.
The user manual functions page is also a good place to look at.
A good question was asked in the post Natural-language date queries: Is it possible to extend this so that I can simply add a the year in the search and only results from that year would show? The answer is yes! Add these functions to your site: The code consists of two functions. The first…
