I need to customize my search results and / or the way my data is indexed. Where can I find documentation?

ElasticPress offers several Features to help you control your search results in your WordPress Dashboard, such as the Weighting Engine and Custom Search Results tool.

However, you may find that you want to customize results or queries even further. ElasticPress provides many hooks and filters to enable you to achieve your desired results, often with just a few lines of code. You can read about all the hooks and filters available in the plugin on the official ElasticPress Plugin Docs site.
