TOP and SCORE

[Markus Dolensky]

My understanding is that SCORE is a measure of the relevance of a 
matching record relative to the other records in the result set (and 
there has been some discussion about calling it RANKING instead).

An example:

input:  TOP=3
output: SCORE={7.5, 76.3, 0.003}

In this example SCORE is expressing the fact that the expected relevance 
of the records with respect to the query parameters is very different. 
Hence, in this context it is certainly useful.

In order to implement Pat's suggestion I propose to use negative 
integers for expressing BOTTOM, e.g., ...

TOP=-3

... to list the three least relevant records.
