Thank you, Mikko! Your filter helped me understand how to do this. I discovered that the percent sign needed to be moved to the end of the term to disable end-of-word matching, as follows:
add_filter( 'relevanssi_fuzzy_query', 'rlv_match_beginning' );
function rlv_match_beginning( $query ) {
return "(relevanssi.term LIKE '#term#%') ";
}
Also, removing the stopword did the trick. I hadn’t discovered stopwords until you pointed them out.
Thanks, again, Mikko for creating such a powerful and useful plugin!
