Use

The search engine service allows you to use the TREX search engine technology to search for business objects. This has the following benefits:

  • You do not require knowledge of the technical implementation of the business objects to perform searches.
  • You can also search for known attribute characteristic values (field contents) even if you do not know the attribute schema of the business object being searched.

The main features of the service are:

  • Quick search using attributes and full-text
  • Extended search (attribute search)
  • Exact search, linguistic search (for example, house/houses), error-tolerant search
  • Search for multilingual objects

The main components are:

  • Interfaces for searching for direct integration in ABAP
  • Interfaces for updating the indexes
  • Indexing service and administration
  • Customizing
Integration

The search engine service is part of the SAP NetWeaver Application Server ABAP (SAP NetWeaver Application Server). It is connected to a TREX system.

The search engine service replicates the business objects from the database into the TREX system. When a user enters a search query, the TREX system responds to it, not the database. As administrator, you complete the initial configuration of the search engine service and monitor it during production operations.

The following figure shows the architecture of the search engine service and its use for both end users and administrators.
