I'd like to search posts by year. For example, I could type in "June 2015" and all posts from that time appear. Or, I could type "2015" and all posts from the year appear.
Currently, I have Relevanssi set to index all public posts and attachments, including all categories and tags. Yet, posts from a searched time (ex, "2015") are not populating, unless the term is in the title or post content.
I can't seem to find a solution anywhere. Hoping for some help!
