Hi, ChiaChen
You need replace {schema},{table},{index_column} according to your schema.
For example, you create a full text index on the column "CONTENT" of table "NEWS" in schema "TEST".
So the query statement will be :
SELECT COUNT(0)FROM m_service_threads WHERE SERVICE_NAME='preprocessor' and thread_method='prep/indexing' and thread_detail like 'TA/TEST:NEWSen.CONTENT%'
