Hi Everyone, We are using lucene,nutch and spring framework to create a specialized search engine. Due to growing traffic we are trying to scale. By doing some tests we found out that the bottle neck was lucene search. We used some heavy traffic simulation and logged the time taken by each portion of the server response and found out that the bulk of the time was spent in searching from lucene index.
In order to accomodate higher traffic we are planning on splitting our application in 2 portions: 1. Web application (on 1 machine) 2. Search application (one more than 1 machine) Each one of the application will reside on a (possibly) separate machines. We are looking forward to scaling by adding more than 1 machine dedicated to searching as lucene search seems to be the bottleneck. Web application will provide the front-end to the user. All static pages, images and the style information will reside on this machine. It will also serve dynamic pages but all the searching will take place on the search application. Web application will send search parameters to the search application and after searching, it will send back the results to the web application which will format it and display it to the user. What we are unable to decide is whether to use RMI ( http://www.soft-amis.com/index.html?return=http://www.soft-amis.com/cluster4spring/index.html cluster4spring )or simple HTTP POST/GET request with response in XML format. We did some research and found out that RMI (with clustering support) might be more suitable for our needs. Unfortunately our team is not familiar with RMI and so we don't know if there will be any issues with it during implementation. Advantage of using simple GET/POST is we have more control which searcher app to use and when. An important criteria for us is to disable searching from the searcher app who's index is being updated. This is very important for us. Is there anyway in RMI to inform the web (client) application that a particular server is unavailable (due to index being updated). We would also like to know if anybody has implemented lucene searching in a similar fashion. Thanks for your help.
