Note: Since I was the first to record this kind of video, the imperfect place please forgive me. This series of courses mainly covers three major parts, one is the principle of search engine, the second is the in-depth analysis of lucene and advanced characteristics, the third is the real-time search of the framework of distributed search and code implementation of the search engine More theoretical explanations, some parts of the content is less, the need for integrity, or as a separate section, may be short video time, good video is a section of sales, I have marked the video of each section of the length, you can selectively purchase for Lucene in-depth analysis and advanced characteristics, basic in the " Lucene principles and Code Analysis of the series, described in the blog, if you do not want to buy a friend can download http://download.csdn.net/detail/forfuture1978/2452992, do not integrate For real-time search of distributed search framework analysis and code implementation, I think the most valuable part is the principle of the framework as well as the code, and some video courses in the video playback process in the field to write code, so the video may be longer, I take is to write the code in advance, in the video just to explain to you, So the time may be shorter.

Course Description:

This course is not limited to how to use Lucene, but with Lucene as an example, through the in-depth analysis of the various modules of search engine design principles and implementation of various modules, and then can jump out of lucene see Search engine system architecture and design ideas. Finally, this course introduces some of the advanced features of Lucene and personalized modifications and interventions that may be involved in building a search engine system using Lucene, and finally gives an example of a real time search system based on Lucene.
