It would be useful if Relevanssi also indexes the Title and Description for each category, because the category archive may be the most relevant result for the search term. For example if somebody searches for 'animals' and there is a category with the title 'Animals' and the category description also includes animals then the main Category archive is probably more relevant than individual posts with that word. Right now the category archive doesn't appear in results at all. Would you please consider adding the ability to index the Category title and description?
Thanks & Regards!
