How can i use ajax for this??

1.Basically whatever the solution , it should be applicable to the search the data which will be in small or huge amount.. 2.My requirement is as follows: i)There will be an admin user who will add the data for the site. ii)Requirement is like,when admin will add the data tht time only XML file will get updated.Otherwise search will done from XML file with the data present at tht time. Basically I want to ignore the trip to the database server... If you are talking about the caching is it feasible solution for it?

My requirement is to search the data from the database.But here one problem is whenever I click for search the data,It will take the trip to database server.Instead of that Is there any other solution where I can keep my data from database and search for it.. 1.Is it possible to do with transfer the data to XML file and search in tht only? 2.Or there is another solution to do this? Please help me..
