This chapter provides reference information on how to use the CTX_ULEXER
PL/SQL package with the user-defined lexer.
CTX_ULEXER
declares the following type:
Name | Description |
---|---|
WILDCARD_TAB | Index-by table type that you use to specify the offset of characters to be treated as wildcard characters by the user-defined lexer query procedure. |
TYPE WILDCARD_TAB IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
Use this index-by table type to specify the offset of those characters in the query word to be treated as wildcard characters by the user-defined lexer query procedure.
Character offset information follows USC-2 codepoint semantics.
