**Formatted Search Using <code>**%SEARCH\{... format="..."\}%**</code> Variable**
%TOC%
## <a name="Preface"> Preface </a>
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. <code>%SEARCH\{ "food" format="| $topic | $summary |" \}%</code>).
## <a name="Syntax"> Syntax </a>
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. <code>header="| \*Topic:\* | \*Summary:\* |"</code>
2. `format="..."` parameter
Use the format paramter to specify the format of one search hit. I.e. `format="| $topic | $summary |"`
Variables that can be used in the format string:
<table border="1" cellpadding="1" cellspacing="0">
<tr>
<th bgcolor="#99CCCC"><strong>Name:</strong></th>
<th bgcolor="#99CCCC"><strong>Expands To:</strong></th>
</tr>
<tr>
<td><code>$web</code></td>
<td> Name of the web </td>
</tr>
<tr>
<td><code>$topic</code></td>
<td> Topic name </td>
</tr>
<tr>
<td><code>$locked</code></td>
<td> LOCKED flag (if any) </td>
</tr>
<tr>
<td><code>$date</code></td>
<td> Time stamp of last topic update </td>
</tr>
<tr>
<td><code>$rev</code></td>
<td> Number of last topic revision, i.e. <code>1.4</code></td>
</tr>
<tr>
<td><code>$wikiusername</code></td>
<td> Wiki user name of last topic update, i.e. <code>%MAINWEB%.<nop>JohnSmith</nop></code></td>
</tr>
<tr>
<td><code>$summary</code></td>
<td> Topic summary </td>
</tr>
<tr>
<td><code>$formfield(name)</code></td>
<td> The field value of a form field, i.e. <code>$formfield(<span style="background:"><font color="">Topic Classification</font></span><a href="http://LOCATION/TopicClassification">?</a>)</code> would get expanded to <code>PublicFAQ</code>. This applies only to topics that have a <span style="background:"><font color="">TWiki Form</font></span><a href="http://LOCATION/TWikiForms">?</a></td>
</tr>
<tr>
<td><code>$pattern(reg-exp)</code></td>
<td> A regular expression pattern to extract some text from a topic, i.e. <code>$pattern(.*?\*.*?Email\:\s*([^\n\r]+).*)</code> extracts the email address from a bullet of format <code>* Email: ...</code>. </td>
</tr>
</table>
**_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.
