SOLR Installation

Version: 7.5.0

First Steps: Get Solr running

Using the plain Solr installation in bin\solr start it with

$> bin/solr start

Then one should basically create a core using

$> bin/solr create_core -c lire

Then you are up to changing the config files to your need. To check if it worked point your browser to http://localhost:[port]/ whereas the port should be stated in your shell, where you started Solr.

Where to learn more?

I assume the better way to learn to handle Solr is by reading the Solr documentation:

  1. Solr Reference Guide
  2. Solr web page
  3. Using Xml messages to update the index

Common Solr Commands

  • Deleting everything in the core: <delete><query>*:*</query></delete>
  • Committing changes: <commit/>

You may also use the browser directly, changing "lire" to the name of the core you are using:

http://localhost:8983/solr/lire/update?stream.body=<delete><query>*:*</query></delete>
http://localhost:8983/solr/lire/update?stream.body=<commit/>

Or of course using curl with direct XML

curl http://localhost:8983/solr/lire/update -H "Content-Type: text/xml" --data-binary '<commit waitFlush="false" waitSearcher="false"/>'

Or using curl with XML files

curl http://localhost:8983/solr/lire/update -H "Content-Type: text/xml" --data-binary @input-data.xml

Solr Cross-Origin Development

If you want to access the Solr server from any other web page, you have to add the following lines to the web.xml file in <solr-version>/server/solr-webapp/webapp/WEB-INF:

<filter>
    <filter-name>cross-origin</filter-name>
    <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
    <init-param>
        <param-name>allowedOrigins</param-name>
        <param-value>*</param-value>
    </init-param>
    <init-param>
        <param-name>allowedMethods</param-name>
        <param-value>GET,POST,OPTIONS,DELETE,PUT,HEAD</param-value>
    </init-param>
    <init-param>
        <param-name>allowedHeaders</param-name>
        <param-value>origin, content-type, accept</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>cross-origin</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
