|

**

** The purpose of this is to test that the fts3_tokenizer() function

|
** can be used as designed by the C-code in the queryTokenizer and
|
||
|
|
** registerTokenizer() functions above. These two functions are repeated

** in the README.tokenizer file as an example, so it is important to
|
||
|
|
** test them.
|
||
|
|
**
|
||
|
|
** To run the tests, evaluate the fts3_tokenizer_internal_test() scalar
|
||
|
|
** function with no arguments. An assert() will fail if a problem is
|
||
|
|
** detected. i.e.:
|

|

** SELECT fts3_tokenizer_internal_test();
