  • This presentation provides a technical overview of EasySearch product from Networked Planet
  • These are the standard problems associated with search.How many times have you heard people use 6 figures to describe the amount of money spent on just their search…. … and then it still didn’t give you the search results you expected it to.
  • EasySearch is a name we’re really happy with, it combined the two most important things we wanted to achieve. The “Search” is obvious, however what we really wanted was “Easy”.
