To support the differing needs for sophisticated, rich searching, fedora 4 comes with a standard mechanism and integration point for indexing content in an external service such as Apache Solr.
Define Indexing Namespace and Mixin in Compact Node Definition of fcrepo4
External indexing relies upon the objects you wish to have indexed to have an indexing:indexable mixin property. Make sure your node definitions contain the following:
fcrepo-kernel/src/main/resources/fedora-node-types.cnd
<indexing = 'http://fedora.info/definitions/v4/indexing#'> [indexing:indexable] mixin - indexing:hasIndexingTransformation (STRING) multiple COPY nofulltext noqueryorder
The standard configuration chain is as follows:
- fcrepo4/fcrepo-webapp/src/main/webapp/WEB-INF/web.xml contains a context-param element with param-name "contextConfigLocation". The param-value points to your spring configuration file, usually a path like WEB-INF/classes/*.xml
- One of you spring configuration files is repo.xml that contains a property repositoryConfiguration defining the location of your repository.json
- fedora-node-types.cnd is defined in you repository.json
