How is relevance score calculated in opensearch?

[sanco]

Hi All,

I want to know what algorithm is used to calculate the relevance score in opensearch?

<relevance:score>${row.score}</relevance:score>

what does this value represents in terms of the relevance of document with the search terms?

what is the relevance algorithm used to determine this score and what is its significance?

I would appreciate any kind of help offered in this direction.

thanks in advance,

Alfresco uses lucene to perform most of it's searches.

You should be able to get some details on how relevance is calculated from the lucene site.

http://lucene.apache.org/

Lucene offers ways to affect the score using boosts, but I don't think that is exposed in Alfresco.
