I am converting a SOLR 4.10 db to SOLR 7.1 It is NOT schemaless - so it uses a ClassicIndexSchemaFactory.
In 4.10, I have a field that is a phone number (here's the schema information for the field): <field name="Phone" type="string" indexed="false" stored="true"/> When inserting documents into SOLR, there are some documents where the value of Phone is an empty string or a single blank space. When running a query against SOLR 4.10, the documents returned that have an empty or single space in Phone, include the phone field in the documents: ... "FirstName":"Bob, No Phone", "Phone":"", "State":"WA" ... "FirstName":"Sandy, No Phone", "Phone":"" "State":"CA" ... "FirstName":"Donald, With Phone", "Phone":"123-123-1234", "State":"NY" ... But when these same rows are inserted into SOLR 7.1, the documents returned for those rows have no Phone field ... "FirstName":"Bob, No Phone", "State":"WA" ... "FirstName":"Sandy, No Phone", "State":"CA" ... "FirstName":"Donald, With Phone", "Phone":"123-123-1234", "State":"NY" ... See how Donald has a phone number because there was a "non-blank" phone number. I also looked at the version of Java installed on the two boxes - the SOLR 4.10 box has java 1.8.0_161, and the SOLR 7.1 box has java 1.8.0_40. I wouldnt think the java version difference would cause that - I believe SOLR just requires 1.8. Is this something that has been added since 4.10? Is there a schema setting or SOLRConfig.xml or Schema.xml setting that can turn the 4.10 behavior back on? Thanks, Rick Hodder
