The ajax filters that BuddyBoss supplies for the Members Directory – profile type and sort order – are both undependable to the point of dysfunction and difficult to modify to the point of dyspepsia at least.
All that we wanted was a simple selector allowing us to return members of particular LearnDash groups when viewing the directory. Using the bp_ajax_query_string filter turned out to be the key, but understanding its peculiar behavior and invisible background relationship (or disrelationship) with Profile Search also turned out to be critical.
A simpler objective was to limit the users shown in the directory to users of the current site (aka “blog”) and to override the “per_page” settings for pagination. Adding pagination links to the top of the directory required directing editing – via addition of a simple template tag – bp_nouveau_pagination( 'top' ) – to our already heavily customized template file buddypress/members/members-loop.php
/**
* In multisite installation, ensure BuddyPress Members Directory counts and displays users of the current site,
* aka "current blog" only
* @param string | array $ajax_query_string A component name or array of arguments modifying the BuddyPress user query
* @note Use a priority of 100 or higher in order to avoid conflicts with bps-search.php
