Dear Wiki user, You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.
The following page has been changed by JayHill: http://wiki.apache.org/solr/DataImportHandler ------------------------------------------------------------------------------ }}} Here we have three queries specified for each entity except the root (which has only two). - * The ''query'' gives the data needed to populate fields of the Solr document in fill-import + * The ''query'' gives the data needed to populate fields of the Solr document in full-import * The ''deltaImportQuery'' gives the data needed to populate fields when running a delta-import * The ''deltaQuery'' gives the primary keys of the current entity which have changes since the last index time * The ''parentDeltaQuery'' uses the changed rows of the current table (fetched with deltaQuery) to give the changed rows in the parent table. This is necessary because whenever a row in the child table changes, we need to re-generate the document which has that field.
