boostQParser and dismax
hello *, i was just reading over the wiki function query page and
found this little gem for boosting recent docs thats much better than
what i was doing before
recip(ms(NOW,mydatefield),3.16e-11,1,1)
my question is, at the bottom it says
The most effective way to use such a boost is to multiply it with the
relevancy score, rather than add it in. One way to do this is with the
boost query parser.
how exactly do i use the boost query parser along with the dismax
parser? can someone post an example solrconfig snippet?
thx much

Congratulations on this....What dotnet library did you use? We are also
using solr in our windows2003/C# environment but currently simply use HTTP
to query and the Dataimport handler to update the indices...

Thanks, it's pretty new (like 2 or 3 days). Still kind of arbitrary
(1 year old = 1/2 the relevance) but it seemed like a decent starting
point.

See the boost link if you haven't already:
http://lucene.apache.org/solr/api/org/apache/solr/search/BoostQParserPlugin.html
The value of the boost ("foo" in that example) is a full sub-query...
meaning you can change it's type
and specify it as {!dismax qf=text pf=text}foo
Or, you could set the defaultType for the subquery to dismax in the
boost itself (and specify the other dismax params globally):
{!boost b=... defType=dismax v=$qq}
&qq=ipod
&qf=text
&pf=text
...
See also the basic rules of LocalParams if you haven't already:
http://wiki.apache.org/solr/LocalParams
And the relevancy faq:
http://wiki.apache.org/solr/SolrRelevancyFAQ#How_can_I_boost_the_score_of_newer_documents
And here's a full URL for you to chew on:
http://localhost:8983/solr/select?q={!boost b=$dateboost v=$qq
defType=dismax}&dateboost=recip(ms(NOW,manufacturedate_dt),3.16e-11,1,1)&qf=text&pf=text&qq=ipod+touch&debugQuery=true
