Back to Indexes

Introduction

The browse indexes for DSpace can be extensively configured. The configuration allows you to take control of the indexes you wish to browse, and how you wish to present the results. With DSpace versions =>3.X, the browse indexes can now be delivered via the SOLR service, if so desired. The browse indexes were previously only delivered via the PostgreSQL/Oracle database service.

Instructions

For DSpace 5.X

For DSpace 4.X

For DSpace 3.X

OLD INDEX PURGE

For DSpace =>5.X

A new command has been introduced with DSpace =>5.X. See below for an example. 

$HOME/bin/dspace index-db-browse -f -d

See step 11 of: https://wiki.duraspace.org/display/DSDOC5x/Upgrading+DSpace

For DSpace <=4.X

Check that you have a backup of the database before doing any purging. You have been warned.

Step 1 - Remove "communities2item" table

Login into the server as the dspace user and then type the following; 

sudo -i

su - postgres

psql dspace

DELETE from communities2item;

\q

exit

exit

exit

Step 2 - Remove all "bi_" tables

I used pgadmin to do a "cascade drop" of all the bi_* tables, where bi = browse index.

Bug Reports

Check SOLR webapp operation

If you have problems with the SOLR webapp, then complete the following to check its operation.

Install the "lynx" application. 

sudo apt-get install lynx

Then type the following in the console: 

lynx http://localhost/solr

You should get the following:

Lynx-solr.png

If not debug the solr webapp until you can.

Remember to restart the Tomcat server for each change you make to a webapp configuration.
