regression=# select to_tsquery( '\'fotballklubber\''); to_tsquery ------------------------------------------------ 'fotball' & 'klubb' | 'fot' & 'ball' & 'klubb' (1 row) So, changed interface to dictionaries, lexize method of dictionary shoud return pointer to aray of TSLexeme structs instead of char**. Last element should have TSLexeme->lexeme == NULL. typedef struct { /* number of variant of split word , for example Word 'fotballklubber' (norwegian) has two varian to split: ( fotball, klubb ) and ( fot, ball, klubb ). So, dictionary should return: nvariant lexeme 1 fotball 1 klubb 2 fot 2 ball 2 klubb */ uint16 nvariant; /* currently unused */ uint16 flags; /* C-string */ char *lexeme; } TSLexeme;
