Re: question about Solr SignatureUpdateProcessorFactory
: Why is also the field name (* above) added to the signature : and not only the content of the field? : : By purpose or by accident? It was definitely deliberate. This way if your signature fields are "fieldA,fieldB,fieldC" then these two documents... Doc1:fielda:XXX Doc1:fieldB:YYY Doc2:fieldB:XXX Doc2:fieldC:YYY ...don't wind up with identical signature alues : I would like to suggest removing the field name from the signature and : not mixing it up. As mentioned, in the typical case it's important that the field names be included in the signature, but i imagine there would be cases where you wouldn't want them included (like a simple concat Signature for building basic composite keys) I think the Signature API could definitely be enhanced to have additional methods for adding field names vs adding field values. wanna open an issue in Jira sith some suggestions and use cases? -Hoss

Re: question about Solr SignatureUpdateProcessorFactory
Why do you want to do this? It'd be the same value, just stored in multiple fields in the document, which seems a waste. What's the use-case you're addressing?

Re: question about Solr SignatureUpdateProcessorFactory
Dear list, another suggestion about SignatureUpdateProcessorFactory. Why can I make signatures of several fields and place the result in one field but _not_ make a signature of one field and place the result in several fields. Could be realized without huge programming?

question about Solr SignatureUpdateProcessorFactory
Dear list, a question about Solr SignatureUpdateProcessorFactory: for (String field : sigFields) { SolrInputField f = doc.getField(field); if (f != null) { *sig.add(field); Object o = f.getValue(); if (o instanceof String) { sig.add((String)o); } else if (o instanceof Collection) { for (Object oo : (Collection)o) { if (oo instanceof String) { sig.add((String)oo); } } } } } Why is also the field name (* above) added to the signature and not only the content of the field? By purpose or by accident? I would like to suggest removing the field name from the signature and not mixing it up. Best regards, Bernd
