How to delete Solr Index

To delete all documents from my Solr index, we have to issue an update request with the  stream.body parameter set to <delete><query>*:*</query></delete>, as with the following URL: 


http://<host>:<port>/solr/update?stream.body=<delete><query>*:*</query></delete>&commit=true


Just replace the placeholder with the correct details. If executed successfully the it will return a response with status = 0 and query execution time.
<response>

<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">3693</int>
</lst>
</response>


If you want to remove indexes of a particular field then specify the field name in the delete query
<delete><query>desc:*</query></delete>


You can also delete a wrongly indexed value from a particular field, just by adding the value in the delete query
<delete><query>desc:wrold</query></delete>

The Externalizable Interface

Before you start exploring Externalization in Java, I would recommend you to gather some knowledge of Serialization in Java because Externalizable is an alternative to Serializable interface. Externalizable interface allows you to customize how serialization is done. By implementing Externalizable you are controlling what gets serialized and what does not get serialized.  Externalizable interface  extends Serializable interface and defines two methods to be overridden by the implementing class.  public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException public void writeExternal(ObjectOutput out) throws IOException Java class implementing Externalizable interface package learn.java.serialization; import java.io.Externalizable; import   java.io.IOException; import   java.io.ObjectInput; import   java.io.ObjectOutput; import   java.util.Date; public class ExternalizableObject implements Exte...

Using Solr Spellchecker from Java

Continuing from my prevoius post Implementing Spellchecker in Solr , we'll now see how to use SorlJ API to fetch spellcheck suggestions through a Java program. public static Map<String, List<String>> getSuggestions(String queryStr){ if (queryStr != null &&  !queryStr.isEmpty()) { try { SolrServer server = new HttpSolrServer("http://localhost:8983/solr ");    ModifiableSolrParams params = new ModifiableSolrParams();    params.set("qt", "/spell");    params.set("q", queryStr);    params.set("spellcheck", "true");    params.set("spellcheck.collate", "true");    QueryResponse response = server.query(params);    System.out.println("response = " + response);    if(response != null){       SpellCheckResponse scr = response.getSpellCheckResponse();     if(scr != null...
