One section of the Berkley University, California has 5 different sites up and running from a long time specifically for their publications. It is a tedious task for a user to search for a specific publication. They will have to go through each individual sites to purchase the publications. To avoid this problem they needed to implement a global search operation to search all the 5 different sites using one main site.
How we have helped: We implemented a solution using indexing method to help them achieve their goal.
We built a custom plugin which can be installed on the sites for the search feature to work seamlessly. They can use this plugin on any number of sites they want.
