: Based on two values in a indexed object in lucene, I am trying to return a : sorted list on that calculation. I was told FunctionQuery was the place to : go. So here is my problem.
take a look at my reply to a similar question to java-user about a month ago... http://www.nabble.com/Re%3A-FunctionQuery-example-request-p3423400.html Note that if you want a strict sort based on a mathematical equation of field values, it might make more sense to impliment a custom sort then to impliment a custom function query -- a function query is designed for when you want a sort by score, but you want that score to be biased according to a a mathematical equation of field values. That said, an description of how to impliment a custom FunctionQuery is included in that link. -Hoss
