Score boosting

[Chamnap Chhorn <ch...@gmail.com>]

Hi everyone,

I have a requirement to achieve, but i can't figure out how to do it. Hope
someone could help me.

Here is the requirement: A book has several keyphrases (available to use in
searching). The author could buy the search result position with these
keyphrases or simply add keyphrases related to this book. Here, I need to
implement the search affected by the position field.

I'm not so sure how to implement this requirement. Hope anyone could help
me!

Thanks for your reply. Do you have other solution? Here each keyphrase must
be matched with the exact and whole world. The problem is that it is a
multivalued column.

Sounds like you want Payloads. I don't think you can guarantee a position,
but you can boost relative to others. You can give one author/book a boost
of 0 for the phrase Cooking, and another author/book a boost of .5 and yet
another a boost of 1.0. For searches that include the phrase Cooking, the
scores should reflect the boosts and the authors that bought the higher
boost value will sort higher. These discuss Payloads (it isn't a trivial
task by the way):
