Overview

DSpace offers two options to index content for Browsing & Searching:

  1. Traditional Browse & Search (via Lucene & Database indexes) - this is enabled by default
  2. Faceted/Filtered Browse & Search (via Solr & DSpace Discovery) - available for XMLUI only and disabled by default

This particular page only describes the "Traditional Browse & Search" indexing processes. For more information on Faceted/Filtered Browse & Search, please see DSpace Discovery, in particular Discovery SOLR Index Maintenance .

Warning

If you are using the SOLR Browse DAOs you don't need to run this script as the data are stored in the SOLR search core. You need to recreate the indexes usign the Discovery maintenance script

Destroy and Rebuild Browse Tables

...

Because Browse Indexes are stored in database tables, remember to run index-init after adding any new definitions in the dspace.cfg to have the indexes created and the data indexed.

Info

Since DSpace 3.0 a SOLR DAOs implementation of the browse system is provided. If you are using the SOLR DAOs you don't need to run the script described in this page but instead use the Discovery maintenance script. Browse indexing in SOLR is done withing the Search Indexing process.
