Website, [url removed, login to view], is the ongoing customization of an open source program, YALD - www.yald.com. Want to upgrade current database search programming to facilitate Boolean searches with results listed in order of relevance. Installation of Sphinx has been suggested by several sources, but am open to other options. I am not a programmer, please request further specific information needed to provide bid. Questions requiring technical info beyond my grasp will be answered by a Zend certified programmer retained for that purpose.
