Hi,
I issued MoreLikeThis query using a uniquekey of a source document, and I
got no match as below (but I can select this document fine in Solr).
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">0</int>
</lst>
<result name="match" numFound="0" start="0" maxScore="0.0"/>
<null name="response"/>
<lst name="interestingTerms"/>
</response>
The query is like this:
http://localhost:8080/solr/dbcollection_1/mlt?&q=uniquekey:20320
However, using select in stead of MLT, this document did return
http://localhost:8080/solr/dbcollection_1/select?&q=uniquekey:20320
when I tried another uniquekey with almost the same document content, Solr
returned match and similar jobs.
http://localhost:8080/solr/dbcollection_1/mlt?&q=uniquekey:20321
When I tried another MLT query where there is empty value on the matching
field, no similar jobs returned as expected, but nonetheless the match
document is returned as expected.
What could cause MLT query return <result name="match" numFound="0"..>
whereas we can select this document fine?
Thanks!
Daniel
