How to get last indexed record in Solr?

I want to know how to get/search last indexed record in Apache Solr..?

When the existing record is updated then it goes to end of all the records...so I want to get that last indexed record.

thanks..

Solution

  • You could add a 'timestamp' field to your Solr schema that puts the current date/time into the record when it is added.

    <field name="timestamp" type="date" indexed="true" stored="true" default="NOW" multiValued="false"/>

    Then, do a sort in descending order by this field and the first record will be the latest one. A query like this should do it:-

    http://localhost:8080/solr/core-name/select/q=*%3A*&start=0&rows=1&sort=timestamp+desc
