SUNScholar/Search Indexes

!!! WARNING !!!

https://jira.duraspace.org/browse/DS-1070

Not a good idea to enable Discovery in DSpace version 1.7.2

Introduction

This wiki help page assumes that you have used the three system setup procedures to install an Ubuntu server with DSpace software.

Before attempting SOLR discovery setup please make sure the following are correct:

1. Tomcat is listening on TCP port 80.
2. The SOLR webapp is correctly published.

Step 1

Setup solr search URL in config file.

nano /home/dspace/dspace-1.8.2-src-release/dspace/config/modules/discovery.cfg

Make sure the solr URL is as follows by removing port 8080. See example below.

##### Search Indexing #####
solr.search.server = http://localhost/solr/search

---

NANO Editor Help

CTL+O	= Save the file and then press Enter
CTL+X	= Exit "nano"
CTL+K	= Delete line
CTL+U	= Undelete line
CTL+W	= Search for %%string%%
CTL+\	= Search for %%string%% and replace with $$string$$
CTL+C	= Show line numbers

Step 2

Please refer to the official DSpace documentation

• https://wiki.duraspace.org/display/DSDOC18/Discovery
• http://www.dspace.org/1_7_1Documentation/Discovery.html

Step 3

Type the following to rebuild the discovery index.

sudo /home/dspace/bin/dspace update-discovery-index -b

Example config for DSpace 1.7.2

##### Search Indexing #####
solr.search.server = http://localhost/solr/search

# Should no solr facet be configured for a certain page, this one will be used as default
#Every solr facet field which ends with _dt will be handled as a date
#Handeling as date implies that {field.name}.year will be used for faceting
solr.facets.search=dc.contributor.author,dc.subject,dc.date.issued_dt

solr.facets.site=dc.contributor.author,dc.subject,dc.date.issued_dt
solr.facets.community=dc.contributor.author,dc.subject,dc.date.issued_dt
solr.facets.collection=dc.contributor.author,dc.subject,dc.date.issued_dt
#solr.facets.item=dc.contributor.author,dc.subject,dc.date.issued_dt


# Put any default search filters here, these filters will be applied to any search in discovery
# You can specify multiple filters by separating them using ,
##Default filters are used for every search in discovery, including the separate scope filters below
#solr.default.filterQuery=location:l2
# You can also specify (additional) filter(s)
## for homepage recent submissions
#solr.site.default.filterQuery=
## for community recent submissions
#solr.community.default.filterQuery=
## for collection recent submissions
#solr.collection.default.filterQuery=
## for searches
#solr.search.default.filterQuery=
## for browsing (not used at the moment)
#solr.browse.default.filterQuery=

# The filters which can be selected in the search form
solr.search.filters=dc.title, dc.contributor.author, dc.date.issued.year, dc.subject, dc.type, dc.description.provenance

# Indexed fields which can sorted on in our search
solr.search.sort=dc.title, dc.date.issued_dt

#Defines whichs fields are indexed as dates
#please be aware that for each date field an _dt will be suffixed so that dc.date.issued will become dc.date.issued_dt
#For each date indexed the year will also be stored separately in a {field.name}.year so it can be used for date faceting
solr.index.type.date=dc.date,dc.date.*

#Recent submission size
solr.recent-submissions.size=10
#The indexed field on which we sort so we can determine which items where recently submitted
recent.submissions.sort-option=dc.date.accessioned_dt

#Use the property below to limit the number of facet filters in the side of the search page
search.facet.max=20

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

OR

lynx http://localhost:8080/solr

You should get the following:

If not debug the solr webapp until you can.

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