: Processing chain (to avoid NFE): via XPath loaded into a field of type : text with a trim and length filter, then via copyField directive into : the tfloat type field
The root of the problem you are seeing is that copyField directives are applied to the *raw* field values -- the analyzer used on your "source" field won't have any effect on the values given to your "dest" field. My suggestion would be to modify the XPath expression you are using to pull data out of your original XML files and ignore "<estimated_hours/>" Alternatively: there are some new UpdateProcessors available in 4.0 that let you easily prune field values based on various criteria (update porcessors happen well before copyField)... http://lucene.apache.org/solr/api-4_0_0-ALPHA/org/apache/solr/update/processor/RemoveBlankFieldUpdateProcessorFactory.html : Problem: : Well, yet another NFE. But this time reported on the text field "s_estimated_hours": I believe this is intentional, but i can understand how it might be confusing. I think the point here is that since the field submitted by the client was named "s_estimated_hours" that's the field used in the error reported back to the client when something goes wrong with the copyField -- if the error message refered to "estimated_hours" the client may not have any idea why/where that field came from. But i can certainly understand the confusion, i've opened SOLR-3657 to try and improve on this. Ideally the error message should make it clear that the "value" from "source" field was copied to "dest" field which then encountered "error" : : WARNUNG: Error creating document : SolrInputDocument[{id=id(1.0)={2930}, s_estimated_hours=s_estimated_hours(1.0)={}}] : org.apache.solr.common.SolrException: ERROR: [doc=2930] Error adding field 's_estimated_hours'='' : at org.apache.solr.update.DocumentBuilder.toDocument(DocumentBuilder.java:333) ... : Caused by: java.lang.NumberFormatException: empty String : at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:992) : at java.lang.Float.parseFloat(Float.java:422) : at org.apache.solr.schema.TrieField.createField(TrieField.java:410) : at org.apache.solr.schema.FieldType.createFields(FieldType.java:289) : at org.apache.solr.schema.SchemaField.createFields(SchemaField.java:107) : at org.apache.solr.update.DocumentBuilder.toDocument(DocumentBuilder.java:312) : ... 11 more -Hoss
