Customer pointed out that:

The index-macro (delivered with Advanced Macro add-on) should have an option to define a set of labels. That would make possible to collect all glossary entries and abbreviations in confluence and automatically create a topic-dependent index as an extract of all possible pages.

There are a lot of macros that are collecting informations with labels used as filters. All of them should provide the same method of using a single label or a set of labels to find pages using all stated labels.
