• Key Concepts: 
  Full-text index is a feature of the SAP TREX component that allows for fast and efficient searching of text-based data. It is based on an inverted index, which is a data structure that stores words and their associated documents. This allows for quick retrieval of documents that contain specific words or phrases. 
  
  How to use it: 
  Full-text indexing can be used to search for documents in SAP TREX. To do this, the user must first create an index on the desired text field. This can be done by using the CREATE INDEX command in the TREX command line interface. Once the index is created, the user can then use the SEARCH command to search for documents containing specific words or phrases. 
  
  Tips & Tricks: 
  When creating an index, it is important to consider the size of the text field and the amount of data that will be indexed. If the text field is too large or contains too much data, it may take a long time to create and maintain the index. Additionally, it is important to consider how often the data will be updated, as this will affect how often the index needs to be updated.
