Metacat

return null if there is no existing SolrDoc for the given pid.

check for existing index document before trying to use existing fields.

allow indexing of RDF documents - provide a sparql query that will return values for the field name. Using measurement_sm initially (a dynamic multivalued solr field). https://projects.ecoinformatics.org/ecoinfo/issues/6253

check for existing documents - don't assume it exists.

Unify solr indexing with an IndexTask that is added to the queue -- allows us to send more than just the systemMetadata to the indexer. Initially this is for READ event counts for each document. https://projects.ecoinformatics.org/ecoinfo/issues/6346

Rename the IndexGenerator to IndexGeneratorTimerTask.

Fixed a bug that when a data file was archived, the solr index for the metadata object still kept the "documents" element.

made the delete method synchronized.

If an object was archived, the solr index will be removed for it.

Use the setting from the metacat-common component.
