Architecture

Structure

Embedded Search comprises the following two software components:

ABAP component (extraxtion layer)
The ABAP component of Embedded Search allows extraction of data from SAP applications for indexing by the indexing layer (TREX).
Search and Classification (TREX) (search engine and indexing layer)
Search and Classification (TREX) provides the search engine. TREX indexes the data extracted from the ABAP system.

Process

Once you have worked through the post-installation tasks for Embedded Search, applications, such as SAP Business Suite, can use Embedded Search.

The figure below illustrates the process flows for the indexing time and runtime:

Indexing time: Embedded Search checks at scheduled times for changes to the indexable SAP Business Suite data. The changes to the data are extracted and passed to Search and Classification (TREX), where they are added to the search index.

Runtime: A search application in SAP Business Suite sends a search query to Embedded Search. This forwards to query to Search and Classification (TREX), which uses search indexes to form a search result and passes this result to Embedded Search. Embedded Search sends the search result to the search application.

This graphic is explained in the accompanying text.

Note Note

Embedded Search is the Enterprise Search component in SAP NetWeaver Application Server ABAP. It can happen that Embedded Search is called Enterprise Search (ABAP) in the SAP Business Suite documentation.
