database update for custom joomla work

on a website I have a custom page that searches a database. I need 2 fields to adjust the way they search. I need “Proj Name” and "subdevision" to be able to take a list of projects. for example: VILLAS AT SUNSET BEACH,VILLAS AT SEACREST BEACH,SEAGROVE HIGHLANDS would find all results that matched that in that field On 2 seperate sites with similar databases I need a search that has no results to go to a specific page on each site letting them know that no results match that search. A page that would say something like “We are sorry but there are no units on the market at this time. Everything meeting this search criteria is either under contract or sold.” On my panamabeachrealty site it should link to article 104 on 30-a-real-estate site it should link to article 83
