Hi, Following is the update request processor chain.
<updateRequestProcessorChain name="DefaultProcessorChain" default="true" > < processor class="solr.TimestampUpdateProcessorFactory"> <str name= "fieldName">index_time_stamp_create</str> </processor> <processor class= "solr.LogUpdateProcessorFactory" /> <processor class= "solr.RunUpdateProcessorFactory" /> </updateRequestProcessorChain> And, here is how the field is defined in schema.xml <field name="index_time_stamp_create" type="date" indexed="true" stored= "true" /> Every time I index the same document, above field changes its value with latest timestamp. According to TimestampUpdateProcessorFactory javadoc page, if a document does not contain a value in the timestamp field, a new Date will be generated and added as the value of that field. After the first indexing this document should always have a value, so why then it gets updated later? I am using Solr Admin UI's Documents tab to index the document for testing. I am using Solr 6.3 in master-slave architecture mode.
