Oracle Text Fails To Index using CHINESE_VGRAM_LEXER (Doc ID 2559107.1)

Last updated on JULY 19, 2019

Applies to:

Oracle Text - Version 11.2.0.4 to 18.5.0.0.0 [Release 11.2 to 12.2]
Information in this document applies to any platform.

Symptoms

On 11.2.0.4 an Oracle Text failed to index / search html with special chinese symbol,

If the html contains a special symbol (e.g. the symbol for 'wong'), then the symbol is not searchable using the contains() operator as it was in Oracle 9i.

The Oracle Text index was created with the Chinese_vgram_lexer defined in the Index DDL.
