Using wildcards in file searches

A wildcard is a symbol representing one or more characters (*, +, ?) or a logical operator (!, $). They are used to define search strings to find field values in a file, or to select files in a file selection box. There are five wildcards that you can use:

You can use wildcards to find field values in a file, or filter the selection when selecting files.

Meaning	Char	Example	Finds
Match any number of characters.	*	R*	R, RA, R123, RCH02, etc.
Match any single alphabetic character.	?	R?C	R1C, R C, ROC, etc.
Match any numbers of characters except zero.	+	R+	R1, RA, RABC, etc.
Match any string containing a given character.	$	$R	ARC, ROC, BAR, 94RC02, etc.
Match any string NOT containing a given character.	!	!R	1, 20, ABC, etc.

Literals

\ is a special character which indicates that the character directly following it should be interpreted literally.

This is useful when special characters in a string (e.g. single or double quotes, or wildcards) need to be treated literally rather than as special characters.

To treat the backslash character literally, use two backslashes.

Example	Finds
1*\$	10$, 100$, 1000$, etc.
\\D*	\Data, \Documents, etc.

Note: The * and ? wildcards, described above, can be used anywhere in Micromine, even when querying SQL databases that also accept % and _ (underscore) wildcard characters.

Wildcards can also be used to set a drillhole database filter or to select wireframes in a wireframe set. See: Wildcards

As an alternative to wildcards, Regular Expressions can be used when using the Find and Replace functions in the File Editor.
