We have a requirement that requires an additive score and I am not sure if it
is possible
and what the right way to go about it is. Assume, there are three fields -
(a) Project name - contains text
(b) Project description - contains text
(c) Profile score - numeric
The basic idea is to implement the score as a linear function of term
frequency for (a), (b) and
add the score in (c). For example, if the project name is "Web PHP - Web Dev
and Web Design" and the project
description is "Web Design and Development", then a search for "Web" should
yield,
score for project name = 150 * 1 + 10 * 2, where the multiplying factor
is 150 for the first occurrence of
of "Web"
and the factor is 10 for the next two occurrences.
score for project description = 200 * 1, where the multiplying factor is
200.
score for profile = 10 * 0.5, where 10 is the multiplying factor and 0.5
is a system generated user score.
The total score would then be, 170 + 200 + 5 = 375.
The DisjunctionMaxQuery seems to yield the maximum score only. From my
understanding, I would
need to do the following -
(1) Create a new similarity function
(2) Write a new Query class extension
(3) Need to write a new linear function ??
It seems to be that some elements are probably already there, and I am not
understanding the
capabilities/possibilities very well.
Thanks in advance.
