 Two parameters can be used to specify a customized search result:
Changed:
<
<
1. header="..." parameter
>
>

1. 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.
Example: header="| *Topic:* | *Summary:* |"
Changed:
<
<
2. format="..." parameter
>
>
Variables that can be used in the header string:

Name: Expands To:
$web Name of the web
$n or $n() New line. Use $n() if followed by alphanumeric character, e.g. write Foo$n()Bar instead of Foo$nBar
$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 (%)
$dollar Dollar sign ($)

2. format="..." parameter

 Use the format parameter to specify the format of one search hit.
Example: format="| $topic | $summary |"
Line: 65 to 75

Here are some samples of formatted searches. The SearchPatternCookbook has other examples, such as creating a picklist of usernames, searching for topic children and more.
 

Bullet list showing topic name and summary

Line: 83 to 94
 In a web where there is a form that contains a TopicClassification field, an OperatingSystem field and an OsVersion field we could write:

| *Topic:* | *OperatingSystem:* | *OsVersion:* |

Changed:
<
<
%SEARCH{ "[T]opicClassification.*?value=\"[P]ublicFAQ\"" scope="text" regex="on" nosearch="on" nototal="on" format="| [[$topic]] | $formfield(OperatingSystem) | $formfield(OsVersion) |" }%

$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

Search with conditional output

A regular expression search is flexible, but there are limitations. For example, you cannot show all topics that are up to exactly one week old, or create a report that shows all records with invalid form fields or fields within a certain range, etc. You need some additional logic to format output based on a condition:

  1. Specify a search which returns more hits then you need
  2. For each search hit apply a spreadsheet formula to determine if the hit is needed
  3. If needed, format and output the result
  4. Else supress the search hit

This requires the TWiki:Plugins.SpreadSheetPlugin. The following example shows all topics that are up to exactly one week old.

Write this:

%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" }%

  • The first line sets the weekold variable to the serialized date of exactly one week ago
  • The SEARCH has a deferred CALC. The $percnt makes sure that the CALC gets executed once for each search hit
  • The CALC compares the date of the topic with the weekold date
  • If topic is older, a <nop> is returned, which gets removed at the end of the TWiki rendering process
  • Otherwise, the search hit is formatted and returned

To get this:

 

Embedding search forms to return a formatted result

Use an HTML form and an embedded formatted search on the same topic. You can link them together with an %URLPARAM{"..."}% variable. Example:

Embedding search forms to return a formatted result

Use an HTML form and an embedded formatted search on the same topic. You can link them together with an %URLPARAM{"..."}% variable. Example:

Write this:

<form action="%SCRIPTURLPATH%/view%SCRIPTSUFFIX%/%WEB%/%TOPIC%">
Find Topics: 
<input type="text" name="q" size="32" value="%URLPARAM{"q"}%" />
<input type="submit" value="Search" />
</form>
Result:
%SEARCH{ search="%URLPARAM{"q"}%" format="   * $web.$topic: %BR% $summary" nosearch="on" }%

To get this:

Find Topics:

Nested Search

Search can be nested. For example, search for some topics, then form a new search for each topic found in the first search. The idea is to build the nested search string using a formatted search in the first search.

Here is an example. We want to search for topics, do a nested search with each hit, and show the result as nested bullets. Parameters like scope="text" regex="on" nosearch="on" nototal="on" are omitted for simplicity.

  • First search:
    • %SEARCH{ "freedom" format="   * $topic" }%
  • Second search. For each hit we want this search:
    • %SEARCH{ "(topic of first search)" format="      * $topic" }%
  • Now we nest the searches. We need to escape the second search, e.g. the first search will build a valid second search string:
    • %SEARCH{ "freedom" format="   * $topic: $n$percntSEARCH{ \"$topic\" format=\"      * $dollartopic" }$nop%\" }%

Note that we escape the second search so that it does not get evaluated by the first search:

  • $percnt to escape the leading percent of the second search
  • \" to escape the qouble quotes
  • $dollar to escape the $ of $topic
  • $nop to escape the }% sequence

Nested Search

Search can be nested. For example, search for some topics, then form a new search for each topic found in the first search. The idea is to build the nested search string using a formatted search in the first search.

Here is an example. Let's search for all topics that contain the word "culture" (first search), and let's find out where each topic found is linked from (second search).

  • First search:
    • %SEARCH{ "culture" format="   * $topic is referenced by: (list all references)" nosearch="on" nototal="on" }%
  • Second search. For each hit we want this search:
    • %SEARCH{ "(topic found in first search)" format="   $topic" nosearch="on" nototal="on" }%
  • Now let's nest the two. We need to escape the second search, e.g. the first search will build a valid second search string. Note that we escape the second search so that it does not get evaluated prematurely by the first search:
    • Use $percnt to escape the leading percent of the second search
    • Use \" to escape the double quotes
    • Use $dollar to escape the $ of $topic
    • Use $nop to escape the }% sequence

Write this:

%SEARCH{ "culture" format="   * $topic is referenced by:$n      * $percntSEARCH{ \"$topic\" format=\"   $dollartopic\" nosearch=\"on\" nototal=\"on\" }$nop%" nosearch="on" nototal="on" }%

Overview

 The %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 |" }%).

By default, the format for displaying a search result is fixed, e.g. a table with rows of topic name and topic summary. 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 (i.e. %SEARCH{ "food" format="| $topic | $summary |" }%).

Syntax

Two paramters can be used to specify a customized search result:

1. header="..." parameter

Use the header paramter to specify the header of a search result. It should correspond to the format of the format parameter. This parameter is optional. I.e. header="| *Topic:* | *Summary:* |"

2. format="..." parameter

Use the format paramter to specify the format of one search hit. I.e. format="| $topic | $summary |"

Variables that can be used in the format string:

Name: Expands To:
<-- -->
up
$pattern(reg-exp) A regular expression pattern to extract some text from a topic, i.e. $pattern(.*?\*.*?Email\:\s*([^\n\r]+).*) extracts the email address from a bullet of format * Email: ....
$locked LOCKED flag (if any)
$web Name of the web
$rev Number of last topic revision, i.e. 1.4
$formfield(name) The field value of a form field, i.e. $formfield(TopicClassification?) would get expanded to PublicFAQ. This applies only to topics that have a TWikiForm
$date Time stamp of last topic update
$topic Topic name
$summary Topic summary
$wikiusername Wiki user name of last topic update, i.e. Main.JohnSmith

Note: For $pattern(reg-exp), specify a RegularExpression that scans from start to end and contains the text you want to keep in parenthesis, i.e. $pattern(.*?(from here.*?to here).*). You need to make sure that the integrity of a web page is not compromised, i.e. if you include a table make sure to include everything including the table end tag.
