====== Experiencias con Apache Solr ======

La motivación para encarar esto justo hoy viene de: [[http://www.olacinc.org/drupal/?q=node/437|Faceted, Work-Centric Moving Image Discovery Interface Demonstration]]. A eso se suma una vieja curiosidad por saber algo sobre Solr, dado su uso en aplicaciones como [[http://vufind.org/|VuFind]] y [[http://code.google.com/p/kochief/|Kochief]] (ex Fac-Back-OPAC).


===== Tutorial =====

2010-10-19. Voy a seguir los pasos del [[http://lucene.apache.org/solr/tutorial.html|Solr tutorial]] para conocer algo sobre este software.

Descarga: http://www.apache.org/dyn/closer.cgi/lucene/solr/ => http://apache.mesi.com.ar//lucene/solr/1.4.1/

http://apache.mesi.com.ar//lucene/solr/1.4.1/apache-solr-1.4.1.tgz

==== Getting Started ====

<code>
$ cd ~/software/A/apache-solr-1.4.1/example/
</code>

<code>
$ java -jar start.jar

Para verificar que el servidor está andando accedo a:

    http://localhost:8983/solr/admin/

===== Interfaces Solr/Python =====

  * [[http://wiki.apache.org/solr/SolPython|SolPython (Solr Wiki)]]
  * [[http://pypi.python.org/pypi/collective.solr|collective.solr]]: collective.solr is an approach to integrate the Solr search engine with Plone. It provides an indexing processor for use with collective.indexing as well as a search API similar to the standard portal catalog. GenericSetup profiles can be applied to set up content indexing in Solr and use it as a backend for Plone's site and live search facilities.
  * [[http://pypi.python.org/pypi/solrpy/|solrpy]]: solrpy is a Python client for Solr, an enterprise search server built on top of Lucene. solrpy allows you to add documents to a Solr instance, and then to perform queries and gather search results from Solr using Python.
