How-to guide:

As Solr uses the OR boolean operator as the default conjunction this will show how to configure a different default operator. In this example, the AND operator is added instead of OR.

1. Stop SolrServices (SolrJetty/SolrApache) on the webserver

2. Locate the Solr search core that needs to be changed (Default location: C:\Bitnami\solr-8.3.1-1\apache-solr\server\solr or Digizuite drive).

3. Open the <CoreName>\Conf\solrconfig.xml file.

4. Find the requestHandler section:
   
   

   <requestHandler name="/select" class="solr.SearchHandler"> <!-- default values for query parameters can be specified, these will be overridden by parameters in the request --> <lst name="defaults"> <str name="echoParams">explicit</str> <int name="rows">10</int> <!-- Default search field <str name="df">text</str> --> <!-- Change from JSON to XML format (the default prior to Solr 7.0) <str name="wt">xml</str> --> </lst> --> ... <!-- <arr name="components"> <str>nameOfCustomComponent1</str> <str>nameOfCustomComponent2</str> </arr> --> </requestHandler>

    

5. Add <str name="q.op">AND</str> to the <lst></lst> section. E.g.
   
   

   <lst name="defaults"> <str name="echoParams">explicit</str> <str name="q.op">AND</str> <int name="rows">10</int> </lst>

    

6. Delete the <CoreName>\Data folder

7. Start SolrServices

8. Repopulate the search from the Digizuite DAM Center.
