Introduction to Apache SOLR 4.0 trial and lucidworks

Apache SOLR 4.0 has been released for a while, and the latest SOLR modification is still very large. Especially from the background management interface, it is easier to experience and manage it. By default, the multi-core mode is used, and multiple collections can be managed, monitored, and optimized. From the perspective of the kernel, SOLR 4 also brings many new things, such as SOLR cloud, realtime get, and NRT (near-real-time search) master/Slave extensions are integrated with zookeeper and join queries.

Install SOLR 4

1. Download solr4 http://lucene.apache.org/solr/

2. decompress the package and enter the example folder.

3. Start SOLR

java -jar start.jar

If no error is reported during startup, SOLR can be used after installation is complete. Open your browser and enter the URL http: // localhost: 8983/SOLR/. The following SOLR interface is displayed:

The new SOLR admin management interface mainly includes dashboard, log, SOLR Collection Management, thread management, and system information. Then each collection has a separate query, retrieval, and other management interface.

Go to collection1 (a collection by default), and you can see the following menu for managing collection:

The interface before SOLR is non-Ajax, and multiple collections do not have a uniform UI interface. You can refer to the previous SOLR series to see what it looked like before SOLR 4.0.

SOLR 4 APIs
Although the background management of solr4 has changed a lot, the URL changes of the API are not great. We listed SOLR
4 api url for your reference.

/admin/file/admin/logging/admin/luke/admin/mbeans/admin/ping/admin/plugins/admin/properties/admin/system/admin/threads/analysis/document/analysis/field/browse/debug/dump/elevate/get/query/replication/select/spell/terms/tvrh/update/update/csv/update/extract/update/json

Currently, there are no ready-to-use modules for integration of SOLR 4 and Drupal. However, because the interaction URL is not changed much, I believe that using some modifications to the existing API can directly integrate Drupal with solr4.

Lucidworks

Finally, we will introduce lucidworks. Lucidworks is an enterprise-level SOLR application, including SOLR integration and various data indexes (file, FTP, database, web-HTTP, hadoop, and Amazon cloud), index management, server monitoring, and so on. Previously called lucidimagination, and then called lucidworks.

The following two documents show the general workflow of lucidworks.

A small detail: When I tested lucidimagination (the predecessor of lucidworksd), I found solr4 and the new admin UI, but when I was testing the latest version, it is strange to find that the old admin UI and beta solr4 are used.
