To enable searching for business objects using information about related business objects, embodiments provide creating a first index of a search engine, wherein creating the first index comprises indexing data objects of at least a first type; creating a relationship index, wherein creating the relationship index comprises indexing relationships of data objects of at least the first type, wherein indexing the relationships comprises mapping relationship type data objects representing the respective relationships into documents and indexing the documents; determining relationships of data objects from at least the relationship index; and searching within related data objects for data objects in compliance with at least one search statement.

Abstract: A method of searching for a data object includes creating an index of data objects and searching for the data object in the index. Creating the index may comprise obtaining data objects from a data source, normalizing the data objects into a standardized format, indexing the data objects, and storing the data objects in a normalized index. Searching for data objects may comprise receiving a search request that includes a search criterion, normalizing the search criterion into a standardized format, and searching within the normalized index for a data object that meets the normalized search criterion.
