====== Searching Evergreen with Solr ======

I think Evergreen is pushing the limits of search within PostgreSQL; I've been working with Solr as an additional interface.

Solr does so much of the features we want in Evergreen search and it's much simpler to extend/improve/customise than what is shown in [[documentation:search_idx_def_example|Example: Adding a Local Subjects (690) search index]]

The current Solr search solution is an add-on to Evergreen but can be integrated on top of the same Apache - a demo is visible at [[http://demo.ils.edoceo.com/sap/sunshine]]

===== Features of Solr =====

  * Relvancy Boosting
  * Boolean Search
  * Multi Language Search
  * Easy Addition of Indexed Fields
  * Faceted Search (media, library, language, subject, &c) - 
  * Templates are savable by a simple query string - [[dev:proposal:search_templates|Search Templates]]

===== Indexing =====

This has to be done from an external script, I've got a stub of one going in PHP working with the Solr JSON interface.  Indexes about 32k records in 5 minutes.

===== Installation =====
