Hi all,
I'm wondering if it's possible to configure solrconfig.xml so that the
updateHandler invokes an updateRequestProcessorChain?
At the moment I have modified the /update requestHandler to invoke an
updateRequestProcessorChain, which is working nicely. The catch is that I
have to POST documents to Solr in order to invoke the /update
requestHandler. The portion of my solrconfig.xml file that achieves what
I've just described is as follows:
...
<requestHandler class="solr.XmlUpdateRequestHandler" name="/update">
<lst name="defaults">
<str name="update.chain">uima</str>
</lst>
</requestHandler>
...
<updateRequestProcessorChain name="uima">
<processor
class="org.apache.solr.uima.processor.UIMAUpdateRequestProcessorFactory">
<lst name="uimaConfig">
<lst name="runtimeParameters"/>
<str name="analysisEngine">/descriptors/CustomAnnotator.xml</str>
... etc etc etc ...
</lst>
</processor>
<processor class="solr.LogUpdateProcessorFactory"/>
<processor class="solr.RunUpdateProcessorFactory"/>
</updateRequestProcessorChain>
...
I'm currently using LucidWorks Enterprise (LWE) to crawl document
collections, and as far as I can tell LWE is using the updateHandler to add
documents into Solr. The /update requestHandler I've experimented with above
is not being invoked. I would therefore like the updateRequestProcessorChain
to execute during the LWE crawl, which is the reason for my original
question: is it possible to configure solrconfig.xml so that the
updateHandler invokes an updateRequestProcessorChain? I've tried the
following in solrconfig.xml but the updateRequestProcessorChain didn't
execute:
...
<updateHandler class="solr.DirectUpdateHandler2">
<maxPendingDeletes>100000</maxPendingDeletes>
<autoCommit>
<maxTime>3600000</maxTime>
</autoCommit>
<lst name="defaults">
<str name="update.chain">uima</str>
</lst>
</updateHandler>
...
Can anyone help me out here? Does what I'm trying to do even make sense from
a Solr perspective? I have already viewed the Solr Wiki entry for
solrconfig.xml
http://wiki.apache.org/solr/SolrConfigXml#Update_Handler_Section here .
Thank you,
Jan
