GraphSearch Configuration

When GraphSearch is initialized after starting PoolParty for the first time, it will create a property file graphsearch.properties under {POOLPARTY_HOME}/config/graphsearch where {POOLPARTY_HOME} is the installation directory of PoolParty which may vary.

The default properties are as follows:

## Remark: equal sign (=) in the value must be escaped with a leading backslash (\)
 
## project: project id | customscheme url
graphsearch.facet=1234-1234-1234-1234
## language: default language
graphsearch.language=en
## Mode: CONFLUENCE | DRUPAL | CUSTOM
graphsearch.mode=CUSTOM
 
## PoolParty URL
ppt.url=http://localhost/PoolParty
 
## Connection to remote store
## Graph URI (leave empty to use default graph)
# store.context=
## Remote store type: GRAPHDB | ALLEGROGRAPH
# store.type=RDF4J
## Connection URL
# store.url=http://localhost:8080/rdf4j-server/repositories/graphsearch
## Credentials
# store.username=admin
# store.password=admin
# store.authentication=BASIC

## Setting to connect Confluence
# confluence.url=http://localhost/confluence
# confluence.user=admin
# confluence.password=admin

## Setting to connect UnifiedViews
# unifiedviews.url=http://localhost/unifiedviews
# unifiedviews.user=admin
# unifiedviews.password=admin
# unifiedviews.externalId=admin

## If true the label of uri filters will be added to the search
# search.include.facet.text=false
## Enable / Disable search interface
# search.include.ui=true
## Synchronization of content based on changes in the thesaurus alias extraction model
# search.sync.enabled=false

## Display
# results.init.horizontal:0-1
# results.init.vertical:0-1

By default, GraphSearch is configured to connect to a PoolParty project, where thesaurus data is used as configuration of search facets, and search indexes are managed by the index server configured for PoolParty, which can be either Solr or Elasticsearch. In such case nothing needs to be configured in the property file, since one can specify all configuration options at the admin panel in the GraphSearch Web UI.

In the case that the search index is an RDF dataset stored in a remote RDF database, the connection properties to the database must be specified after uncommenting Line 15, 17, 19, 21, 22 of the property file. GraphSearch supports all the mainstream opensource and commercial RDF databases, including GraphDB and Allegrograph. The format of connection URL will vary according to the database type, for example:

# Allegrograph
store.type=ALLEGROGRAPH
store.url=http://localhost:10035/repositories/graphsearch
 
# GraphDB
store.type=GRAPHDB
store.url=http://localhost:7200/repositories/graphsearch

When the RDF dataset is stored in a named graph, the graph URI must be specified. Otherwise GraphSearch will query the default graph. The credentials for a user which has read permission on the configured repository and graph must be specified.

Last but not the least, Line 11 must be commented out if GraphSearch should connect to the remote RDF database. Then facet configurations and other configuration options can be specified at the admin panel in the GraphSearch Web UI, which will be explained in detail in GraphSearch on RDF Dataset.
