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™.

Perform fuzzy searches

A fuzzy search is a search for text that matches your clue closely instead of exactly. Fuzzy searches can also be referred to as pattern searches. Fuzzy searches help you return results of interest even when the search terms themselves are misspelled in the documents you are searching.

Important: Fuzzy or pattern searches can be performed only on columns whose etx indexes were created with the

WORD_SUPPORT
= PATTERN

index parameter.

This section describes the types of fuzzy searches you can perform with the module and describes, in general terms, how the search engine scores both word-level matches and document matches.
