TWiki Formatted Search Results
Inline search feature allows flexible formatting of search result
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 |" }%).
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 |
$topictext | Formatted topic text |
$locked | LOCKED flag (if any) |
$date | Time stamp of last topic update, i.e. 21 Nov 2024 - 18:20 |
$isodate | Time stamp of last topic update, i.e. 2024-11-21T18:20Z |
$rev | Number of last topic revision, i.e. 1.4 |
$wikiusername | Wiki user name of last topic update, i.e. Main.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.
