1. A method comprising: performing a first search in a set of fields of a set of searchable objects; after said performing the first search, mapping the set of fields to a set of searchable fields, wherein the set of fields comprises a first set of fields defined by a configurable field mappings file, wherein the configurable field mappings file provides an abstraction layer between a plurality of search engines and the set of searchable objects, first set of fields is a subset of a set of all the fields of the searchable objects, the fields of the searchable objects are defined when the searchable objects are designed, said mapping is performed subsequent to a design of the searchable objects, accessible by a search center through a search index that corresponds to the configurable field mappings file, and the configurable field mappings file is configured to define a relationship between the fields of the searchable objects and the searchable fields; modifying the set of searchable fields by modifying the fields of searchable objects within the configurable field mappings file, wherein said modifying is based at least in part on a second set of fields that are fewer than all the fields of the searchable objects, and the first and second sets of fields are distinct; updating a search index in response to said modifying the set of searchable fields; and performing a second search in the set of fields based at least in part on the updated search index.
