Hi I am using Lucene for the MIT's Open Courseware website as a part of enhancement we need to have better control over the order of search results. Currently, for a webpage indexing is done for metadata like Title, Description, Resource, Author, Keyword etc. and the HTML content itself. Order by relevance functionality provided by Lucene assigns better rank to metadata than the HTML content (due to score normalization), but, the requirement is to control the order of results within different metadata fields. Example: Title should get more weight that Author irrespective of the number of words in the field Description should get more weight than Resource even though the description always has more words than the Resource metadata Question: Is there an easy way to multiply the score with some Multiplication Factor" at the time of generating indexes? Can the Boost Factor be applied to pump-up the relevance of one Name:Value pair as against another Name:Value pair? How effective is this boosting? Does the score/relevance get multiplied by the Boost factor? Thanks Kanwal
