TWiki Formatted Search Results

Inline search feature allows flexible formatting of search result

Overview

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:
$n	New line
$web	Name of the web
$topic	Topic name
$locked	LOCKED flag (if any)
$date	Time stamp of last topic update, i.e. 07 Jan 2009 - 17:35
$isodate	Time stamp of last topic update, i.e. 2009-01-07T17:35Z
$rev	Number of last topic revision, i.e. 1.4
$wikiusername	Wiki user name of last topic update, i.e. Faemalia.JohnSmith
$username	User name of last topic update, i.e. JohnSmith
$summary	Topic summary
$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
$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: ....

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.
