• Key Concepts: 
  Compound index is a type of index in SAP that combines multiple fields into one index. It is used to improve the performance of searches and queries in the TREX search engine. It is also used to reduce the amount of data stored in the database. 
  
  How to use it: 
  Compound indexes are created in the TREX search engine by combining multiple fields into one index. This allows for faster searches and queries, as well as reducing the amount of data stored in the database. The fields that are combined into a compound index must be related to each other, and must have similar data types. 
  
  Tips & Tricks: 
  When creating a compound index, it is important to consider which fields should be combined and which should remain separate. Combining too many fields can lead to slower performance, while combining too few can lead to unnecessary data storage. It is also important to consider the data types of the fields being combined, as incompatible data types can lead to errors.
