Filter the data server-side, use XHR on the client to request the results, and the DOM to generate the markup. Since you would probably prefer XHR anyway in order to get the latest data efficiently and user-friendly when turning the page, no major modifications to the business logic would be necessary. The worse alternative is to send the client the whole list, but generate only a part of it (per page) either server-side or client-side. > Should I have a "hidden" list with every item and then create the > displayed list(s) from it? Then it would not work without client-side scripting, and initial loading would take longer. Also, the search would be on the last snapshot of the data, not necessarily the current data. Note that either way you can cache the data server-side in a session, potentially reducing database load. -- PointedEars FAQ: <http://PointedEars.de/faq> | SVN: <http://PointedEars.de/wsvn/> Twitter: @PointedEars2 | ES Matrix: <http://PointedEars.de/es-matrix> Please do not Cc: me. / Bitte keine Kopien per E-Mail.
