Question

I have used the command below to search for and list all the topics which contain the word PPI.

%SEARCH{ "PPI" scope="topic" nosearch="on" nototal="on" header="---+++PPI forms $n" format="[[$topic]] $n" }% 

The result is:

PPI forms

ListOfPPIforms

PPIform

PPIformCreator

PPInewcandidate

But I want just the topics which start with the word PPI. What is the modification to be made in the search command ? I tried

%SEARCH{ "PPI*"...

Thanks Franz!. That does it. Where can I get help on the these parameters that can be used ? (like type, scope, nosearch, nototal, regex etc and also if I want a list of topics ending with a word etc). I tried looking into FormattedSearch but I couldn't get much help.

All possible parameters of SEARCH are described on VarSEARCH. On RegularExpression you find some necessary regex basics. With release 4.2 you alternatively can use QuerySearch (type="query") constructs to find and format what you need. Great stuff! Try it!

%SEARCH{ "name~'PPI*'" scope="topic" type="query" nosearch="on" nototal="on" header="---+++PPI forms $n" format="[[$topic]] $n" }%

What does ^ mean in a search ? As per an example in RegularExpression, it looks like ^ means excluding. but in the answer to my query, it looks like starting with.

^ (tophat) normally means starting with as you say. When it is in brackets [^text] it means NOT text

Maybe some day someone writes a TWiki specific RegularExpressionTutorial, although there are plenty of infos out there in the wild (Internet), there are even books about the (secret) art of regex (got one as christmas present a few years ago).
