Hi,
I've been chasing this bug and tried couple of options and found out that these
issues fix my problem:
1. The number of words in match string is capped at 16.
2. These characters in the match string I replaced with spaces.
case ',':
case '.':
case '/':
case '-':
case ':':
case '\'':
case '"':
case '(':
case ')':
case '\\':
case '@':
Was it a bug or was it the limitation? Or Perhaps I missed the documentation on
FTS4.
best regards,
Radzi.
