Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
HCL OneDB™ extensions and DataBlade® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.
Excalibur Text Search DataBlade® Module User's GuideThese topics describe the module and how to access and use its components.
OverviewThis section provides an overview of the module.
Components of the Excalibur Text Search DataBlade® moduleThe module has three principal components: the etx access method, the etx_contains() operator, and the supporting routines defined for the DataBlade® module.
The etx_contains() operatorYou use the etx_contains() operator to perform searches of etx indexes. This section explains how to perform basic searches such as keyword and Boolean searches by using the etx_contains() operator.
