Theme Indexing

By default, themes are indexed in English and French, for which you can index document theme information. A document theme is a concept that is sufficiently developed in the document.

Search document themes with the ABOUT operator and retrieve document themes programatically with the CTX_DOC PL/SQL package.

Enable and disable theme indexing with the index_themes attribute of the BASIC_LEXER preference type.

You can also index theme information in other languages, provided that you loaded and compiled a knowledge base for the language.
