I am trying to configure automatic deduplication for SOLR 1.4 in Vufind.
I followed:
http://wiki.apache.org/solr/Deduplication
Actually nothing happens. All records are being imported without any
deduplication.
What am I missing?
Thanks
Markus
I did:
- create a duplicated set of records, only shifted their ID by a fixed
number

solrconfig.xml
<requestHandler name="/update" class="solr.XmlUpdateRequestHandler" >
<lst name="defaults">
<str name="update.processor">dedupe</str>
</lst>
</requestHandler>
<updateRequestProcessorChain name="dedupe">
<processor
class="org.apache.solr.update.processor.SignatureUpdateProcessorFactory">
<bool name="enabled">true</bool>
<bool name="overwriteDupes">true</bool>
<str name="signatureField">dedupeHash</str>
<str name="fields">reference,issn</str>
<str
name="signatureClass">org.apache.solr.update.processor.Lookup3Signature</str>
</processor>
<processor class="solr.LogUpdateProcessorFactory" />
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>

In schema.xml I added the field
<field name="dedupeHash" type="string" stored="true" indexed="true"
multiValued="false" />

If I look at the created field "dedupeHash" it seems to be empty...!?
