Search indexes
General Information
- Description
-
Search indexes are derivative metadata structured for and stored in Apache Solr index stores.
- Purpose
-
Provides search functionality.
- Quick Facts
-
A distinct Solr index is created for the Catalog, Databases, and UWDC categories in the Coordinated Discovery Platform and for each citation database implemented in Blacklight.
These are transitory application data sets. The size of the dataset vary from 1000s of records for citation database to more 12 million records for the catalog dataset.

NA
- Correctness
-
Mappings between source data records in MARC, MODS, or local schemas and the semantics of Solr record schema must preserve the semantic intent of source data relative to the discovery and display requirements of the consuming application.
- Representative Record
-
NA These are derivative records. There is no authoritative instance of this data.
- Dependencies
-
Source MARC, MODS, and local schema records.
Access & Use
- Delivery Modalities
-
Via Solr APIs to consuming applications: Coordinated Discovery Platform and Blacklight instances.
- Lifecycle
-
The indexes are periodically rebuilt and incrementally updated based on changes detected in the source data. There is no preservation or archiving.
- Disposition
-
Stored on LCB machines hosting Solr, their associated storage, and backups.
- Relevant Processes
-
The data are derived through ETL workflows from source data sets.
- Constraints
-
No applicable constraints,.
