Hi,

I'm a newbie to Solr and have a question about the example in FunctionQuery.

I've read the document of these:

    http://wiki.apache.org/solr/FunctionQuery
    http://wiki.apache.org/solr/SolrQuerySyntax

and don't understand the example in FunctionQuery.

It's said that the query below searches the field boxname with value =
"finxbox", then order the results by x * y * z.

    q=boxname:findbox+_val_:"product(product(x,y),z)"

What does the "+" between findbox _val_ stand for? Is it mean "order by"?

According to the document, the score is replaced by "+_val_:...". I tried
it,
but the result is not like that. The scores are changed but I cannot
tell how it works.

Thanks.

chlo
