Multicolumn search using text index very slow.

  Hi Gurus,

I have implemented a multicolumn search in one of the tables with over 120 columns. The search uses context index built around 20 columns together. The performance was good for normal indexing but after using priority listing and scoring, the performance went bad. Is there a definitive way to establish multicolumn search in Oracle with scoring and prioritizing. While creating a context index, I used 'MULTI_COLUMN_DATASTORE' in the preferance. Is there any other way to create a text index in favor of performance?

Thanks for the response.

Regards

KLA
