change sort order for MoreLikeThis

[Renz Daluz-2]

Hi,

I'm looking at changing the result order when searching by MLT. I tried the
sort=<field>,<order> but it's not working. I check the wiki and can't find
anything. Is there a way to do this?

Thanks,
/Laurence

You can boost the similarity field matches, if you want. Look for mlt.boost
at http://wiki.apache.org/solr/MoreLikeThis

Cheers

Avlesh,
     You lost me.  How does boosting change the sort order?  What about
sorting on a field that is not the mlt field?

I checked the javadoc of Lucene's MoreLikeThis and MoreLikeThisQuery and
don't see any method regarding sorting at all.  So my guess is we can't sort
the MoreLIkeThis result in Solr until this is supported in Lucene.

Absolutely sorry about that Bill :(

How does boosting change the sort order?

What I really meant here is that if you have more than one "similarity"
fields in you MLT query, you can boost the results found due to one over the
other. It was not at all aimed to be an answer for sort. Actually, I was too
prompt to respond!

What about sorting on a field that is not the mlt field?

Haven't tried this yet. It would be surprising if it does not work as
expected.

Thanks guys.
I tried to boost it instead (as sort looks like not supported) but it's not
taking effect. Here are the parameters that I'm using:

I want to boost by time_published field and I enable mlt.boost
&bf=recip(rord(time_published),1,1000,165)^1500&qt=mlt&mlt.boost=true

Oh and yes, I tried to sort that is not mlt field and it's not taking
effect:
Here the whole parameters that I'm using:

mlt.fl=text,title&tie=0.01&mlt.mintf=1&mlt.match.include=true&fl=tagged_bucket,tagged_entities&bf=recip(rord(time_published),1,1000,165)^1500&qt=mlt&mlt.minwl=3&mm=5&mlt.boost=true&qf=text^0.5+title^0.4++description^0.01+keywords^0.01+bestlink_keywords^0.1+authors_t^0.05&mlt.maxwl=20&mlt.maxntp=200&mlt.maxqt=10&mlt.interestingTerms=details&rows=200&mlt.mindf=3&pf=text^300+title^10+tagged_entities^200+inbound_text^1+bestlink_keywords^1&q=id:story|25584945c&ps=1&sort=time_published+desc

I just opened a JIRA on this:

https://issues.apache.org/jira/browse/SOLR-1545

I have attached a patch there that seems to work for me.
