Hi Parth, I implemented DFR algorithms in Xapian as a part of GSOC last year under the mentorship of Olly. This year, I want to work on analyzing and optimizing the performance of the DFR algorithms and comparing them with BM25.I also want to work on profiling the query expansion schemes and test the relevance(precision and recall) / speed(time taken) of the

...Please let me know if you have any comments or any questions on points I mentioned. Sorry for the delay. I would like to mention that I am doing active preparation by reading Xapian codebase and literature. Thank you.
