Thread: Tsearch2 - list of words or phrase with count

hello,

I have table with text attribute and fulltext index...

is it possible to do query with result:

word or phrase, count

for example:
SELECT word, my_count(word) FROM table WHERE expression.

   word    |   my_count
----------|------------
  'hello'  |      3
  'bye'    |      4
  'yellow' |      1
  'blue'   |      5

thanx, hlavki
