Hi all, We have successfully integrated Solr in our application, and now we are facing a requirement where the application should be able to search for duplicate records in Solr core based on equality in 3 distinct fields.
Tried using SignatureUpdateProcessorFactory as described in https://cwiki.apache.org/confluence/display/solr/De-Duplication and Lookup3Signature and everything seems to work fine, signature field is being filled with unique hash values. One issue we have, is that we need to pass to SignatureUpdateProcessorFactory the stemmed value of 1 of 3 fields. Currenty, the following documents produce different hash values, and we need them to produce unique. Analysis for field1 and values "value1_a" and "value1_b" produce stemmed value "value1" documentA: { field1: value1_a, field2: value2, field3: value3, signature: hash_value1 } documentB: { field1: value1_b, field2: value2, field3: value3, signature: hash_value2 } I would like to ask whether it is possible to have required behavior, and some tips about how to accomplish this task. Thank you in advance, Leonidas
