Document Presentation and Highlighting

Typically, a Text query application allows the user to view the documents returned by a query. The user selects a document from the hitlist and then your application presents the document in some form.

With interMedia Text, you can render a document in different ways. For example, you can present documents with query terms highlighted. Highlighted query terms can be either the words of a word query or the themes of an ABOUT query in English.

You can also obtain theme information from documents with the CTX_DOC PL/SQL package.

Table 1-1 describes the different output you can obtain and which procedure to use to obtain each type:
