Weighted Frequency

Like the Frequency module, the Weighted Frequency (Wfreq) module scores results based on the frequency of user query terms in the result.

Additionally, the Weighted Frequency module weights the individual query term frequencies for each result by the information content (overall frequency in the complete data set) of each query term. Less frequent query terms (that is, terms that would result in fewer search results) are weighted more heavily than more frequently occurring terms.

The Weighted Frequency module ignores matches due to query expansion (that is, such matches are given a rank of 0).

Note: Due to performance issues, it is not recommended to use the Weighted Frequency module with standalone relevance ranking (that is, per-query relevance ranking).
