This if for the FAQ,

What parameters affects the scoring of a document ?

A comprehensive itemized list will be greatly appreciated. If not, just send
the
items you are aware of and we will construct a single list.

Here are a starting list but it is based mostly on speculations:

(*) boost factor

(*) location of the match inside the field (?)

(*) length of the matched field (?)

(*) number of matches (e.g. in 'any word' matching ) (?)

(*) phrase similarity to actual matched sequence (?)

(*) global frequency of matched terms (that is, in the entire index) (?)

(*) frequency of the matched terms in the document field (?)

(*) the relative scoring of other hits (scoring dependency) (?)


Thanks,

Tal
