Hi, please take a look at Alba, a framework which simplifies the development of new Solr plugins. You can write a plugin (e.g. custom function to be used to boost/sort your docs or a custom Response Writer) in literally five lines of code.
More specifically I think these two examples could be useful. This is the basic example, which shows you how to write a function to calculate the length of a text field and how to use that information for boosting/sorting/filtering: https://github.com/leonardofoderaro/alba/wiki/Your-first-Function-Query:-the-title-length Here is a slightly more advanced example, how to a discount on books older than X years: https://github.com/leonardofoderaro/alba/wiki/discounting-old-books Disclaimer 1: it has never been used in production.... yet ;-) Disclaimer 2: I'm the author of the Alba Framework Should you have any questions / issues / hints / PR on how to improve it please let me know. best regards, Leonardo On Tue, Sep 29, 2015 at 8:36 PM, bbarani <bbar...@gmail.com> wrote: > Hi, > > We have a price field in our SOLR XML feed that we currently use for > sorting.
