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™.

Create word lists and a user-defined character setTo prevent stopwords from being indexed, always associate a stopword list with an etx index. This section describes how to create a stopword list based on the file of stopwords provided by the module.

Create word lists and a user-defined character set

To prevent stopwords from being indexed, always associate a stopword list with an etx index. This section describes how to create a stopword list based on the file of stopwords provided by the module.

The provides three built-in character sets (ASCII, ISO, and OVERLAP_ISO) that are used to determine which characters are indexed. If the character sets provided do not index the desired characters, you can define your own character set.

This section describes how to create a user-defined character set that is similar to the ASCII character set but also indexes hyphens.
