Hey Alessandro,
it seems that the edismax MLThandler is not able to work correctly with
a solr cloud/sharding:
https://issues.apache.org/jira/browse/SOLR-4414
Using the MLThandler we got randomly a response for only very few
requests, while the MLTcomponent works fine (except for the problem I
encountered...)
Best wishes,
Jan

Hey Jan, any reason you are using the MLTComponent, instead of a specific
Request Handler with the MLT query parser ?
<requestHandler name="/getSimilar" class="solr.SearchHandler">
<lst name="defaults">
<!-- Query settings -->
<str name="title">Entities Similarity</str>
<str name="defType">edismax</str>
<str name="rows">5</str>
<str name="fl">*,score</str>
<str name="echoParams">explicit</str>
<str name="wt">json</str>
<str name="q">{!mlt qf=field1,field2,field3,field4 mintf=1
mindf=5 maxqt=50 v=$entity_id}</str>
<!-- Default Similarity Parameters-->
<str name="entity_id">0</str>
</lst>
</requestHandler>
This should solve easily your problems,
Cheers

Hello,
I want to use the moreLikeThis Component to get similar documents from a
sharded SOLR. This works quite well except for the fact that the
documents
in the moreLikeThis-list only contain the id/unique key of the documents.
Is it possible to get the other fields? I can of course do another query
for the given IDs, but this would be complicated and very slow.
For example:
http://mysolrsystem/?q=id:524507260&mlt=true&mlt.fl=title&mlt.mintf=0&indent=true&mlt.match.include=true&fl=title,id,topic
creates
(...)
<lst name="moreLikeThis">
<result name="524507260" numFound="5" start="0" maxScore="4.583166">
<doc><str name="id">646199803</str></doc>
<doc><str name="id">613210832</str></doc>
<doc><str name="id">562239472</str></doc>
<doc><str name="id">819200034</str></doc>
<doc><str name="id">539877271</str></doc>
</result>
(...)
I tried to modify the fl-parameter, but I can only switch the ID-field in
the moreLikeThis-Documents on and off (the latter resulting in empty
document tags). In the result list however, the fl-fields are shown as
specified.
I would be very grateful for help.
Best wishes,
Jan Maas
