Subject Measuring precision and recall in lucene to compare two sets of results
Date Mon, 07 May 2012 01:38:09 GMT

I am facing the following problem

For a given set of queries i retrieve the top n results  . Then I make some
changes to the index and then retrieve the top n results for the new index
Is there any way to measure or quantify the quality of the new results as
compared to the first set of results ?
