Question : Oracle Search Features

Do any Oracle search products (for example, Oracle Text, Oracle Secure Enterprise Search or others) allow a search based on a category/category search terms selection?

I'd like to enable a user to search the Oracle database using a computer mouse and a predefined set of categories and a set of search terms associated with each category. Perhaps Oracle Portal can be a solution.

Thank you for your help.

Text will likely do what you are after.  You can add themes and use the ABOUT function.

Depending on how you set it up you can use the Fuzzy, stemming and/or soundex to help locate the results.  You can also set up synonyms to even further refine the results.

For the little you mentioned about your exact requirements I would also look at the CTXRULE index to set up a classification system:
