/**

|
* SearchIndex is the base index class. Each connector will provide a subclass of this that

|
|
* This class is responsible for:
|
|
*
|
|
* - Taking index calls adding classes and fields, and resolving those to value sources and types
|
|
*
|
|
* - Determining which records in this index need updating when a DataObject is changed
|
|
*
|
|
* - Providing utilities to the connector indexes
|
|
*
|
|
* The connector indexes are responsible for
|
|
*
|
|
* - Mapping types to index configuration
|
|
*
|
|
* - Adding and removing items to index
|
|
*
|
|
* - Parsing and converting SearchQueries into a form the engine will understand, and executing those queries
|
|
*
|
|
* The user indexes are responsible for
|
|
*
|
|
* - Specifying which classes and fields this index contains
|
|
*
|
|
* - Specifying update rules that are not extractable from metadata (because the values come from functions for instance)
