MLT and facetting

Hi,

I am trying to combine the mlt functionality with facets, but Solr throws org.apache.solr.common.SolrException: ":"Unable to compute facet ranges, facet context is not set".

What I am trying to do is quite simple, find similar documents using mlt and group these using the facet parameter. When using mlt and facets separately everything works fine, but not when combining the functionality.

In the above example I would like to facet on Journalnummer, thus grouping several documents based on Journalnummer.

Hope someone can help me, and thanks in advance.

RE: MLT and facetting

Posted by "Martin Frank Hansen (MHQ)" <MH...@kmd.dk>.

Hi Dave, 

Thanks for your suggestion, I was under the impression that you could do it in one-search approach. But if that’s not possible I will try to divide into two searches. 

Is the best way to do this through Solrj? 

Best regards

Martin

Hi Martin,

I have no idea on this, as the case has not been active for almost 2 years.
Maybe I can try to follow up.

Faceting by default will show the list according to the number of occurrences. But I'm not sure how it will affect the MLT score or how it will be output when combine together, as it is not working currently and there is no way to test.

Regards,
Edwin

RE: MLT and facetting

Posted by "Martin Frank Hansen (MHQ)" <MH...@kmd.dk>.

Hi Dave, 

The problem is that we have different levels of metadata and documents. 
The documents are arranged such that we have a case for which there are multiple documents (files). When we use the mlt function, we do it on file-level, but it needs to be displayed at case level, which means that we need to group files that are connected to the same case. 

Hope this makes sense.

Re: MLT and facetting

Posted by Zheng Lin Edwin Yeo <ed...@gmail.com>.

Hi Martin,

I have no idea on this, as the case has not been active for almost 2 years.
Maybe I can try to follow up.

Faceting by default will show the list according to the number of
occurrences. But I'm not sure how it will affect the MLT score or how it
will be output when combine together, as it is not working currently and
there is no way to test.

Regards,
Edwin

RE: MLT and facetting

Posted by "Martin Frank Hansen (MHQ)" <MH...@kmd.dk>.

Hi Edwin, 

Ok that is nice to know. Do you know when this bug will get fixed? 

By ordering I mean that MLT score the documents according to its similarity function (believe it is cosine similarity), and I don’t know how faceting will affect this score? Or ignore it all together? 

Best regards

Martin

Hi Martin,

According to the JIRA, it says it is a bug, as it was working previously in Solr 4. I have not tried Solr 4 before, so I'm not sure how it works.

For the ordering of the documents, do you mean to sort them according to the criteria that you want?

Regards,
Edwin

Re: MLT and facetting

Posted by Zheng Lin Edwin Yeo <ed...@gmail.com>.

Hi Martin,

According to the JIRA, it says it is a bug, as it was working previously in
Solr 4. I have not tried Solr 4 before, so I'm not sure how it works.

For the ordering of the documents, do you mean to sort them according to
the criteria that you want?

Regards,
Edwin

RE: MLT and facetting

Posted by "Martin Frank Hansen (MHQ)" <MH...@kmd.dk>.

Hi Edwin,

Thanks for your response. Are you sure it is a bug? Or is it not meant to work together? 
After doing some thinking I do see a problem faceting a MLT-result. MLT-results have a clear ordering of the documents which will be hard to maintain with facets. How will faceting MLT-results deal with the ordering of the documents? Will the ordering just be ignored?

Best regards

Martin

Hi Martin,

I also get the same problem in Solr 7.7 if I turn on faceting in /mlt requestHandler.

Found this issue in the JIRA:
https://issues.apache.org/jira/browse/SOLR-7883
Seems like it is a bug in Solr and it has not been resolved yet.

Regards,
Edwin

Re: MLT and facetting

Posted by Zheng Lin Edwin Yeo <ed...@gmail.com>.

Hi Martin,

I also get the same problem in Solr 7.7 if I turn on faceting in /mlt
requestHandler.

Found this issue in the JIRA:
https://issues.apache.org/jira/browse/SOLR-7883
Seems like it is a bug in Solr and it has not been resolved yet.

Regards,
Edwin

RE: MLT and facetting

Sorry forgot to mention that we are using Solr 7.5.

Hi Edwin,

Thanks for your response. 

Yes you are right. It was simply the search parameters from Solr. 

The query looks like this:

http://.../solr/.../mlt?df=text&facet.field=Journalnummer&facet=on&fl=id,Journalnummer&q=id:*6512815*

best regards,

Hi Martin,

I think there are some pictures which are not being sent through in the email.

Do send your query that you are using, and which version of Solr you are using?

Edwin

RE: MLT and facetting

Posted by "Martin Frank Hansen (MHQ)" <MH...@kmd.dk>.

Hi Edwin,

Thanks for your response. 

Yes you are right. It was simply the search parameters from Solr. 

The query looks like this:

http://.../solr/.../mlt?df=text&facet.field=Journalnummer&facet=on&fl=id,Journalnummer&q=id:*6512815*

best regards,

Martin

Do send your query that you are using, and which version of Solr you are using?
