   * The search parameters class, which represents the settings for the current search -- query, page size, facet list, etc.  This class has routines for processing user input, or all parameters can be set individually by code.  A search options object is used for validation.
-  * The search results class, which actually performs searches (usually with the help of a search parameters object, though it also has some static methods for retrieving records by ID) and turns them into an array of record drivers (described below).

 Base classes are provided that implement common functionality for all three of these areas.  To search different data sources (Solr index, WorldCat API, etc., etc.), subclasses with implementation-specific details for interacting with various low-level [[Search Service|search services]] are provided.
+=== Record Loader ===
+In early versions of VuFind 2.x, the search classes were also used for loading single records. In later releases, this functionality was moved to a stand-alone \VuFind\Record\Loader class, which interfaces with the same [[Search Service|search services]] as the search classes.
