title: php Search using sessions
body: <p>Can someone suggest some reading for database search operation using sessions or some other best practice. 
  i have a scenario where the user search for events with different filters. i get them through ajax an display them. then the user can filter on current results. upon clicking a filter i get the new results from the back-end. Right i am sesnding the clicked filters in an array to back-end querying the database for every click . this is not an ideal approach. i heard sessions can help for storing search results thereby extracting it when applying new filters on the existing rsultset with out querying database .  Any suggestions?</p>
  
  <p>I am usng Laravel and Mysql</p>
