David de Kleer commented on SOLR-7739:
--------------------------------------
Hi Alessandro,
All right, I've managed to build SOLR from the Github mirror, with your patch
applied. I thought you could use it like this?
{code}
<!-- classification -->
<updateRequestProcessorChain name="classification">
<processor class="solr.ClassificationUpdateProcessorFactory">
<str name="inputFields">q_website</str>
<str name="classField">labels</str>
<str name="algorithm">bayes</str>
</processor>
<processor class="solr.LogUpdateProcessorFactory"/>
<processor class="solr.RunUpdateProcessorFactory"/>
</updateRequestProcessorChain>
<requestHandler name="/update" class="solr.UpdateRequestHandler">
<lst name="defaults">
<str name="update.chain">classification</str>
</lst>
</requestHandler>
{code}
But how is it possible to train a model? I can't trace any activity of the
classification updateRequestProcessorChain on an update (labels is a
multivalued string btw, don't know if that is a problem). Or am I doing
something wrong?
With kind regards,
David
