Subject Relevancy Practices
Date Thu, 29 Apr 2010 14:14:51 GMT
I'm putting on a talk at Lucene Eurocon (
on "Practical Relevance" and I'm curious as to what people put in practice for testing and
improving relevance.  I have my own inclinations, but I don't want to muddy the water just
yet.  So, if you have a few moments, I'd love to hear responses to the following questions.

What worked?  
What didn't work?  
What didn't you understand about it?  
What tools did you use?  
What tools did you wish you had either for debugging relevance or "fixing" it?
How much time did you spend on it?
How did you avoid over/under tuning?
What stage of development/testing/production did you decide to do relevance tuning?  Was that
timing planned or not?
