More information

By default Relevanssi blocks all one-letter search terms from the search, no matter what the minimum word length setting is. If you want to allow one-letter search terms, return false for this filter hook:

add_filter( 'relevanssi_block_one_letter_searches', '__return_false' );

If you want to allow one-letter highlights in excerpts, see relevanssi_allow_one_letter_highlights.
