Expression Types

Agent Ransack supports the following expression types:

•Boolean

•Regular expression

•DOS

Boolean Expressions

Boolean expressions combine individual search phrases using the AND, OR, and NOT operators. For more information see Boolean Expressions.

Regular Expression

Agent Ransack uses a Perl compatible regexp syntax when evaluating Regular Expressions. Perl compatible regexp syntax is based around the Boost regular expression engine and includes not only the functionality of the 'classic' regular expression engine but also additional Perl style expression enhancements detailed here: http://www.boost.org/doc/libs/release/libs/regex.

Basic regular expressions can be built using the Expression Wizard

DOS Expressions

DOS expressions are usually used to specify groups of files. Use a semi-colon to specify multiple groups, e.g.

The expression *.cpp;*.h searches for files that end with .cpp or .h

For more information see DOS Expressions.
