3. New features in the 2.x versions

In TIGERSearch 2.1 the following features have been introduced:

Query processing efficiency has been hugely improved for queries using regular expressions.

Additional indexing strategies have been implemented. These strategies increase query processing efficiency up to 50%.

The statistical viewer (introduced as statistical export in TIGERSearch 2.0) has been improved in many details.

There have been several minor improvements and bugfixes.

In TIGERSearch 2.0 the following features have been introduced:

The graphical user interface of the TIGERSearch software suite has been reimplemented. All important features can now be accessed directly from the GUI.

The following utilities have been added to the TIGERSearch query tool: bookmarks, syntax highlighting of corpus queries, and statistical export.

Corpus queries can be specified graphically, i.e. queries can be drawn in an intuitive way.

TIGERSearch has been internationalized, i.e. Unicode characters can be used in corpus queries and any Unicode character will also be rendered in corpus visualization.

Templates, a modularization concept for corpus queries, have been introduced.

The TIGERSearch manual can now be accessed from the GUI. It is also available as a PDF file for high-quality printing.

The TIGERSearch implementation is based on Java 1.4. Thus, many platform-dependent dialogs such as printing or file dialogs are much easier to handle.
