Until I began my current research project earlier this year, my work has focused primarily on small, geographically circumscribed groups of scientists, philosophers, and other intellectuals. Consequently, I've never had much use for databases in my research. Now that I'm beginning my dissertation research in earnest, I am being forced to deal with a very new challenge: collecting and organizing information on hundreds of individuals, publications, and organizations from all over the world. Now, if you're like me, you find the prospect of having to collect birth, death, education, and employment records for the subjects of your research to be an exceedingly dull exercise, but one you need to have finished before you can actually begin to sit down and write. Fortunately, with OpenRefine (formerly GoogleRefine) and Freebase you can automate most of this initial data collection process.

Most of the applications must have a some kind of a search function. The problem is that search functions are often huge resource hogs and they can kill the performance of our application by causing heavy load to the database. That is why transferring that load to an external search server is a great idea. This is the first part of my Spring Data Solr tutorial. During this tutorial we will implement a search function to a todo application which is the example application of my Spring MVC Test tutorial. The requirements of our search function are simple. It must return a list of todo entries which title or description contains the used search term. The search result page must also provide a link to the page used to view the information of a todo entry. Before we can start the implementation of our search function, we need to take a look at the Solr search server. This blog entry provides us the basic information about Solr and it is divided into three parts: The first part gives us a brief introduction to Solr and its data model. The second part describes how we can create a schema for our
