Error tracking in search engine development

In this paper, we describe a tool that allows one to track the output of every module of a search engine. The tool provides the ability to perform pseudo error-correction by allowing the user to modify these outputs or tune parameters of the modules to check for improvement of results. Often it is important to see if certain surface level changes can help in the improvement of the result quality. This is crucial since it saves the immediate need to make changes in the system in terms of resource updation or development efforts. We describe query processing pipeline in sufficient detail and then show the efficacy of our tool for an example in Marathi along with giving a thorough error analysis for the example considered. We believe this paper will establish that such a tool is of significant importance for instant detection and correction of errors along with giving the readers an idea on how to develop the same.
