Re: How to Create a weighted function (dismax or otherwise)

[aster]

Are there any best practices or preferred ways to accomplish what I am
trying? 

Do the params for defType, qf and bf belong in a solr request handler? 

Is it possible to have the weights as variables so they can be tweaked till
we find the optimum balance in showing our results?

Thanks!

How to Create a weighted function (dismax or otherwise)

[aster]

I am trying to create a feature that allows search results to be displayed by
this formula sum(weight1*text relevance score, weight2 * price). weight1 and
weight2 are numeric values that can be changed to influence the search
results.

I am sending the following query params to the Solr instance for searching.

q=red
defType=dismax
qf=10^name+2^price

My understanding is that when using dismax, Solr/Lucene looks for the search
text in all the fields specified in the qf param.

Currently my search results are similar to those I get when qf does not
including a price. I think this is because price is a numeric field and
there is not text match.

Is it possible to rank search results based on this formula -
sum(weight1*text relevance score, weight2 * price).

Thanks!
