Hi,
I am trying to construct a timestamp-boosted query comprising two weighted
fields: "title" and "body":
{!boost b=recip(ms(NOW/HOUR,submit_date),3.16e-11,1,1)}
{!type=dismax qf='title^10 body^1' v=$term}
$term=apple
I expect the given example query provided above to search fields "title"
and "body" using keyword "apple" and adjust the order of the results by the
submission date "submit_date".
However, the query just throws the NullPointerException exception: [1].
Could you please help me out with this issue?
I am using Solr 4.10.3+cdh5.8.2+434 - part of Cloudera 5.8.2 package.
Best,
Gin
