32 # <a name="TWiki Formatted Search Results"></a> TWiki Formatted Search Results
34 _Inline search feature allows flexible formatting of search result_
36 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 |" }%`).
38 ## <a name="Syntax"></a> Syntax
40 Two parameters can be used to specify a customized search result:
42 1. `header="..."` parameter
44 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. <br /> Example: `header="| *Topic:* | *Summary:* |"`
46 2. `format="..."` parameter
48 Use the format parameter to specify the format of one search hit. <br /> Example: `format="| $topic | $summary |"`
50 Variables that can be used in the format string:

111 <td> The field value of a form field; for example, <code>$formfield(TopicClassification)</code> would get expanded to <code>PublicFAQ</code>. This applies only to topics that have a [[Main/TWikiForms]]</td>

115 <td> Form field value, "<tt>- </tt>" hyphenated each 10 characters </td>

126 <td><code>$pattern(reg-exp)</code></td>
127 <td> A regular expression pattern to extract some text from a topic. For example, <code>$pattern(.*?\*.*?Email\:\s*([^\n\r]+).*)</code> extracts the email address from a bullet of format <code>* Email: ...</code>. </td>
130 <td><code>$n</code> or <code>$n()</code></td>
134 <td><code>$nop</code> or <code>$nop()</code></td>
135 <td> Is a "no operation". This variable gets removed; useful for nested search </td>
138 <td><code>$quot</code></td>
139 <td> Double quote (<code>"</code>). Alternatively write <code>\"</code> to escape it </td>
142 <td><code>$percnt</code></td>
143 <td> Percent sign (<code>%</code>) </td>
146 <td><code>$dollar</code></td>
147 <td> Dollar sign (<code>$</code>) </td>
151 **_Note:_** For `$pattern(reg-exp)`, specify a [[RegularExpression]] that scans from start to end and contains the text you want to keep in parenthesis, like `$pattern(.*?(from here.*?to here).*)`. You need to make sure that the integrity of a web page is not compromised; for example, if you include a table make sure to include everything including the table end tag.

207 ### <a name="Nested Search"></a> Nested Search
209 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.
211 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).
214 - `%SEARCH{ "culture" format=" * $topic is referenced by: (list all references)" nosearch="on" nototal="on" }%`
215 - Second search. For each hit we want this search:
216 - `%SEARCH{ "(topic found in first search)" format=" $topic" nosearch="on" nototal="on" }%`
217 - Now let's nest the two. We need to escape the second search, e.g. the first search will build a valid second search string. Note that we escape the second search so that it does not get evaluated prematurely by the first search:
218 - Use `$percnt` to escape the leading percent of the second search
219 - Use `\"` to escape the double quotes
220 - Use `$dollar` to escape the `$` of `$topic`
221 - Use `$nop` to escape the `}%` sequence
225 `%SEARCH{ "culture" format=" * $topic is referenced by:$n * $percntSEARCH{ \"$topic\" format=\" $dollartopic\" nosearch=\"on\" nototal=\"on\" }$nop%" nosearch="on" nototal="on" }%`
