use of edu.harvard.iq.dataverse.search.SolrSearchResult in project dataverse by IQSS.

the class SavedSearchServiceBean method makeLinksForSingleSavedSearch.

/**
 * The "Saved Search" and highly related "Linked Dataverses and Linked
 * Datasets" features can be thought of as periodic execution of the
 * LinkDataverseCommand and LinkDatasetCommand. As of this writing that
 * periodic execution can be triggered via a cron job but we'd like to put
 * it on an EJB timer as part of
 * https://github.com/IQSS/dataverse/issues/2543 .
 *
 * The commands are executed by the creator of the SavedSearch. What happens
 * if the users loses the permission that the command requires? Should the
 * commands continue to be executed periodically as some "system" user?
 *
 * @return Debug information in the form of a JSON object, which is much
 * more structured that a simple String.
