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.
Data typesThis section describes the data types that come with the module.
The etx_HiliteType data type
The viewer_doc fieldThe viewer_doc field contains the document that has been searched. The offsets contained in the vec_offset field are relative to this document.

The viewer_doc field

The viewer_doc field contains the document that has been searched. The offsets contained in the vec_offset field are relative to this document.

The etx_ViewHilite() routine manipulates the vec_offset and viewer_doc data returned by the etx_GetHilite() or etx_HiliteDoc() routines.

You can also use standard routines, such as ifx_lo_open() and ifx_lo_read(), or DataBlade® API large object routines, such as mi_lo_open() and mi_lo_read(), to manipulate etx_HiliteType objects.
