%SEARCH{...}% variable documented in TWikiVariables has a fixed format for the search result, that is, a table consisting of topic names and topic summaries. Use the format="..." parameter to specify a customized format of the search result. The string of the format parameter is typically a bullet list or table row containing variables (such as %SEARCH{ "food" format="| $topic | $summary |" }%).
header="..." parameter
Use the header parameter to specify the header of a search result. It should correspond to the format of the format parameter. This parameter is optional. header="| *Topic:* | *Summary:* |"
2. format="..." parameter
Use the format parameter to specify the format of one search hit.
format="| $topic | $summary |"
Variables that can be used in the format string:
| Name: | Expands To: |
|---|---|
$web | Name of the web |
$topic | Topic name |
$topic(20) | Topic name, "- " hyphenated each 20 characters |
$topic(30, -<br />) | Topic name, hyphenated each 30 characters with separator "-<br />" |
$topic(40, ...) | Topic name, shortended to 40 characters with "..." indication |
$parent | Name of parent topic; empty if not set |
$parent(20) | Name of parent topic, same hyphenation/shortening like $topic() |
$text | Formatted topic text. In case of a multiple="on" search, it is the line found for each search hit. |
$locked | LOCKED flag (if any) |
$date | Time stamp of last topic update, e.g. 05 Nov 2024 - 16:30 |
$isodate | Time stamp of last topic update, e.g. 2024-11-05T16:30Z |
$rev | Number of last topic revision, e.g. 1.4 |
$username | Login name of last topic update, e.g. jsmith |
$wikiname | Wiki user name of last topic update, e.g. JohnSmith |
$wikiusername | Wiki user name of last topic update, like Main.JohnSmith |
$createdate | Time stamp of topic revision 1.1 |
$createusername | Login name of topic revision 1.1, e.g. jsmith |
$createwikiname | Wiki user name of topic revision 1.1, e.g. JohnSmith |
$createwikiusername | Wiki user name of topic revision 1.1, e.g. Main.JohnSmith |
$summary | Topic summary |
$formname | The name of the form attached to the topic; empty if none |
$formfield(name) | The field value of a form field; for example, $formfield(TopicClassification) would get expanded to PublicFAQ. This applies only to topics that have a TWikiForm |
$formfield(name, 10) | Form field value, "- " hyphenated each 10 characters |
$formfield(name, 20, -<br />) | Form field value, hyphenated each 20 characters with separator "-<br />" |
$formfield(name, 30, ...) | Form field value, shortended to 30 characters with "..." indication |
$pattern(reg-exp) | A regular expression pattern to extract some text from a topic (does not search meta data; use $formfield instead). In case of a multiple="on" search, the pattern is applied to the line found in each search hit.• Specify a RegularExpression that covers the whole text (topic or line), which typically starts with .*, and must end in .* • Put text you want to keep in parenthesis, like $pattern(.*?(from here.*?to here).*) • Example: $pattern(.*?\*.*?Email\:\s*([^\n\r]+).*) extracts the email address from a bullet of format * Email: ... • This example has non-greedy .*? patterns to scan for the first occurance of the Email bullet; use greedy .* patterns to scan for the last occurance • Limitation: Do not use .*) inside the pattern, e.g. $pattern(.*foo(.*)bar.*) does not work, but $pattern(.*foo(.*?)bar.*) does • Note: Make sure that the integrity of a web page is not compromised; for example, if you include an HTML table make sure to include everything including the table end tag |
$n or $n() | New line |
$nop or $nop() | Is a "no operation". This variable gets removed; useful for nested search |
$quot | Double quote ("). Alternatively write \" to escape it |
$percnt | Percent sign (%) |
$dollar | Dollar sign ($) |
%SEARCH{ "FAQ" scope="topic" nosearch="on" nototal="on" header=" * *Topic: Summary:*" format=" * [[$topic]]: $summary" }%
To get this:
TopicClassification field, an OperatingSystem field and an OsVersion field we could write:
| *Topic:* | *OperatingSystem:* | *OsVersion:* | %SEARCH{ "[T]opicClassification.*?value=\"[P]ublicFAQ\"" scope="text" regex="on" nosearch="on" nototal="on" format="| [[$topic]] | $formfield(OperatingSystem) | $formfield(OsVersion) |" }%
To get this:
| Topic: | OperatingSystem: | OsVersion: |
|---|---|---|
| IncorrectDllVersionW32PTH10DLL | OsWin | 95/98 |
| WinDoze95Crash | OsWin | 95 |
%SEARCH{ "__Back to\:__ TWikiFAQ" scope="text" regex="on" nosearch="on" nototal="on" header="TWiki FAQs:" format=" * $pattern(.*?FAQ\:[\n\r]*([^\n\r]+).*) [[$topic][Answer...]]" }%
To get this:
TWiki FAQs:
%SEARCH{ "culture" format=" * $topic is referenced by: (list all references)" nosearch="on" nototal="on" }%
%SEARCH{ "(topic found in first search)" format="$topic" nosearch="on" nototal="on" separator=", " }%
$percnt to escape the leading percent of the second search
\" to escape the double quotes
$dollar to escape the $ of $topic
$nop to escape the }% sequence
%SEARCH{ "culture" format=" * $topic is referenced by:$n * $percntSEARCH{ \"$topic\" format=\"$dollartopic\" nosearch=\"on\" nototal=\"on\" separator=\", \" }$nop%" nosearch="on" nototal="on" }%
To get this:
$dollarpercntSEARCH{ for level three, $dollardollarpercntSEARCH{ for level four, etc.
%SEARCH{ "\.*" scope="topic" regex="on" nosearch="on" nototal="on" order="modified" reverse="on" format="| [[$topic]] | $wikiusername | $date |" limit="7" }%

%CALC{$SET(weekold, $TIMEADD($TIME(), -7, day))}% %SEARCH{ "." scope="topic" regex="on" nosearch="on" nototal="on" order="modified" reverse="on" format="$percntCALC{$IF($TIME($date) < $GET(weekold), <nop>, | [[$topic]] | $wikiusername | $date | $rev |)}$percnt" limit="100" }%
weekold variable to the serialized date of exactly one week ago
$percnt makes sure that the CALC gets executed once for each search hit
weekold date
<nop> is returned, which gets removed at the end of the TWiki rendering process
%URLPARAM{"..."}% variable. Example:
Write this:

<input type="submit" value="Search" />
</form>
