Xapian currently supports Tf-Idf weighting scheme. It has some normalisations (described by SMART) already implemented. More normalisations can be added if we make some extra stats available to the weighting scheme. The new normalisations have shown to outperform others in certain cases.

We will also compare the effectiveness of different normalisations. Xapian-evaluation will be used for this.
