Apache solr Installation

- Install jdk first

- Download apache solr from:

- Extract it anywhere. Open command prompt. Go to the directory folder for the following path: apache-solr-3.6.2/example/

- Now to start solr, execute: java –jar start.jar

- Solr has inbuilt data for testing purposes. Using this command "java -jar post.jar *.xml", we can add the data to solr indexing to test if its working fine or not. The instructions are given here:


- We can check if solr is working fine or not with this link: http://localhost:8983/solr/admin/ping


- Now press ctrl+c to stop apache solr

We learnt about integration of an existing xml file and configuration of solr. Now we will try database integration with MySQL. 

- For this, we need the MySQL connector which will establish connection between apache solr and mysql:

- Extract the zip file and copy the .jar file to apache-solr-3.6.2/example/lib directory

- Now we need to add “data Import” request handler that will create a url to import data from the database. We need to add a request handler to solrconfig.xml file, and also need to define a file where we will define which table and fields needs to be indexed. The handler code is as follows:

Apache Solr installation

More details are available at

- Now the data-config.xml file will be something like this: More details on this is also available on the same page -


- Next is the schema.xml file where you need to describe about the fieldtype you are using and the field information. You will find more details on schema.xml here: The files we discussed will be placed at E:/apache-solr-3.6.2/example/solr/conf. Please take a backup of the original file first

- Check if the information added to the file is right or not by executing the ping.- http://localhost:8983/solr/admin/ping

- Now we need to import data of configured database by using this link: http://localhost:8983/solr/dataimport?command=full-import


How to integrate it with php?

- Get the php client library from:

- Then we need to create a php file which will make a call using that library. The code of that php file will be like this:

require_once( 'SolrPHPClient/Apache/Solr/Service.php' );
$solr = new Apache_Solr_Service( 'localhost', '8983', 'solr/');
$ping = $solr->ping();
if ( ! $ping ) {
 echo 'Solr service not responding';

$offset = 0;
$limit = 10;
  $queries = array(
    'test string',
    'sort:post_date desc'

  foreach ( $queries as $query ) {
    $response = $solr->search( $query, $offset, $limit );
    if ( $response->getHttpStatus() == 200 ) { 
      // print_r( $response->getRawResponse() );
      if ( $response->response->numFound > 0 ) {
        echo "$query";

        foreach ( $response->response->docs as $doc ) { 
          echo "$doc->id --- $doc->post_title";
    else {
      echo $response->getHttpStatusMessage();

This code will ping to apache server. If the ping is successful, it will try to search a string "test string" in your default  search field that you set in solrconfig.xml. The $offset and $limit will define the total number of records. If it finds the result, it will print the id and title of record. Otherwise, it prints the error message.
