Fwd: Score and searching

Hi. I'm a little confused about how to obtain score values when performing
search operations.

Which one will be the correct process?

1 - Perform a search operation
2 - Go through QueryResult RowIterator and NodeIterator simultaneously. With
NodeIterator you get the node and with RowIterator you get the score. I'm
assuming that NodeIterator and RowIterator return data in the same order.

or

1 - Perform a search operation
2 - Use only QueryResult RowIterator. You get the score and path property,
and with the path property you obtain the Item through the session object.
But as a drawback you have to do a cast to javax.jcr.Node and you must
assume that a path property should be present.

Thanks Marcel, I didn't saw that point of the spec.

Best regards,

Hi Martin,

I'd say both are correct and feasible. personally I prefer the second 
approach because I don't have to use two iterators simultaneously.

the jcr:path property *must* always be present in a result row, see 
section 8.5.2.2 of the spec. so, you can be sure that it is always there.

regards
