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.
Database Extensions User's GuideThe HCL OneDB™ Database Extensions User's Guide explains how to use the database extensions that come with HCL OneDB™: Large Object Locator, MQ messaging, binary data types, basic text search, node data type, HCL OneDB™ web feature service for Geospatial Data, and SQL packages.
Basic Text SearchYou can perform basic text searching for words and phrases in a document repository stored in a column of a table.
Basic text search queriesYou run basic text search queries with the bts_contains() search predicate.
Boolean operatorsBoolean operators combine terms in logical combinations. You can use the operators AND, OR, and NOT, or their equivalent special characters, in the bts_contains() search predicate.
NOT operatorUse the NOT Boolean operator in combination with the AND operator (or its equivalent symbols) when you want to search for documents that do not contain a specified term or phrase.

NOT operator

Use the NOT Boolean operator in combination with the AND operator (or its equivalent symbols) when you want to search for documents that do not contain a specified term or phrase.

The NOT operator can also be denoted with an exclamation point (!) or with a minus sign (-).

The following search predicates find documents that contain the term UNIX, but not the term Windows:

bts_contains(column, ' UNIX AND NOT Windows ')

bts_contains(column, ' UNIX AND !Windows ')

bts_contains(column, ' +UNIX -Windows ')

The minus sign (-) can be used with the plus sign (+), but not with the AND operator.
