An Introduction to Wildcard Searches with Inspyder Finder

This guide gives a brief introduction to using wildcard matching within Inspyder Finder.

What are Wildcard Searches?

Wildcard searches are a simple way of easily matching patterns of text. The pattern can be very straight-forward, or very complex. We've included wildcard support in Inspyder Finder to make it easier for you to find complicated items, or groups of items, on your site.

Basic Wildcards

The basic wildcard character ('*') lets us match zero or more characters in the search pattern. For example; 'a*.html' matches:

• "a.html"
• "ab.html"
• "abc.html"
• etc.

To match a single character, we use the question-mark character '?'. For example; 'a?.html' will match the following:

• aa.html
• ab.html
• ac.html
• etc.

It will NOT match words like:

• a.html
• abc.html

Ranges

To match a character within a range (for example, a numeric character, 0 to 9) we can use ranges. A range is encapsulated within square brackets, [], and contains the set of characters to search for. For example, if we wanted to match 'inventoryX.html' where the 'X' is any numeric digit, we could write inventory[0123456789].html. This will match the following:

• inventory1.html
• inventory2.html
• inventory3.html
• etc.

It will NOT match words like:

• inventory12.html

As a shorthand, the following is also valid: inventory[0-9].html

Multiple ranges within a single set of brackets is acceptable (for example, the letters A to F and the numbers 0 to 9). For example; inventory[A-F0-9].html will match:

• inventory1.html
• inventoryA.html
• inventoryB.html
• inventoryF.html

It will NOT match words like:

• inventoryG.html

It's important to note that a range only matches a single character. To find inventoryXX.html, we'd have to do the following: inventory[0-9][0-9].html. If the search is case sensitive, then [A-Z] and [a-z] are different ranges.

Alternates

We can specify matches that take the form "one or the other" by using alternates. Alternates are enclosed in curly brackets, {}, and each alternate is separated by a comma. For example, if we wanted to find all the words that start with 'ins' and end with 'pyder' or 'ite' we would use the following syntax: Ins{pyder,ite}. This will match the following:

• Inspyder
• Insite

But it will NOT match:

• Inspect

Literals

To match a special character 'as is' (such as '*' or '?'), then it must be preceded with a backslash ('\') in the query text. For example; 'question\?' will match the following:

• question?

But it will NOT match:

• question!

The same holds true for the '{', '}', '[' and ']' characters.
