SID-01708: Formatted Search with a unique Condition

Category:	CategorySearch	Server OS:		Last update:	10 years ago

Is it possible to create a formatted search that displays all topics in a web where the first letter of the topic name is a specific letter.

For example, a search to display all topics in the web that begin with the letter 'a'. I am not quite sure if string manipulation is possible in Twiki's markup languge.

Thanks for your help,

James

Discussion and Answer

This is a simple SEARCH. Use these parameters:

"a" scope="topic" topic="a*"

Details in VarSEARCH.

Corollary question: How to display a list of topics where the Topic name is for example (note use of wild cards ????-??-??-*?

That's still rather easy: a SEARCH with the following parameters: ".4-.2-.2-.*" type=regex - see VarSEARCH and RegularExpression for examples. The regular expression is the perl style, not the shell-style, though: "." is any character, "-?" is an optional minus sign and "-*" are zero or more minus signs. Still, the examples on RegularExpression should get you going.

A modified regular expression that find the indicated pattern: ".{4}-.{2}-.{2}-.*"
