Symptoms
The AUTO_LEXER is not returning some values after migration from WORLD_LEXER.We have a table with a CLOB column where we store some data in XML format and we search via INPATH, ie
WHERE CONTAINS (XML,'(( (2005) INPATH(/record/extend/identifier) ))' ) > 0
For the WORDL_LEXER I get results but the AUTO_LEXER returns zero rows.
Looks clear why the INPATH in case of term '2005' and with AUTO_LEXER is not returning rows.
WORLD_LEXER is creating the tokens '2005' & 'C' when the AUTO_LEXER just only 'C-2005'.
Changes
Switching from WORLD_LEXER to AUTO_LEXER.Cause
