25 # <a name="TWiki Formatted Search Results"></a> TWiki Formatted Search Results
27 _Inline search feature allows flexible formatting of search result_
29 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 |" }%`).
31 ## <a name="Syntax"></a> Syntax
33 Two parameters can be used to specify a customized search result:
35 1. `header="..."` parameter
37 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. <br /> Example: `header="| *Topic:* | *Summary:* |"`
39 2. `format="..."` parameter
41 Use the format parameter to specify the format of one search hit. <br /> Example: `format="| $topic | $summary |"`
43 Variables that can be used in the format string:
45 <table border="1" cellpadding="0" cellspacing="0">

103 <td><code>$formfield(name)</code></td>
104 <td> The field value of a form field; for example, <code>$formfield(TopicClassification)</code> would get expanded to <code>PublicFAQ</code>. This applies only to topics that have a [[Main/TWikiForms]]</td>
107 <td><code>$formfield(name, 10)</code></td>
108 <td> Form field value, "<tt>- </tt>" hyphenated each 10 characters </td>
111 <td><code>$formfield(name, 20, -<br />)</code></td>
112 <td> Form field value, hyphenated each 20 characters with separator "<tt>-<br /></tt>" </td>
115 <td><code>$formfield(name, 30, ...)</code></td>
116 <td> Form field value, shortended to 30 characters with "<tt>...</tt>" indication </td>
119 <td><code>$pattern(reg-exp)</code></td>
120 <td> A regular expression pattern to extract some text from a topic. For example, <code>$pattern(.*?\*.*?Email\:\s*([^\n\r]+).*)</code> extracts the email address from a bullet of format <code>* Email: ...</code>. </td>
123 <td><code>$n</code> or <code>$n()</code></td>
127 <td><code>$nop</code> or <code>$nop()</code></td>
128 <td> Is a "no operation". This variable gets removed; useful for nested search </td>
131 <td><code>$quot</code></td>
132 <td> Double quote (<code>"</code>). Alternatively write <code>\"</code> to escape it </td>
135 <td><code>$percnt</code></td>
136 <td> Percent sign (<code>%</code>) </td>
139 <td><code>$dollar</code></td>
140 <td> Dollar sign (<code>$</code>) </td>
144 **_Note:_** For `$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.
146 ## <a name="Nested Search"></a> Nested Search
148 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.
150 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.
153 - `%SEARCH{ "freedom" format=" * $topic" }%`
154 - Second search. For each hit we want this search:
155 - `%SEARCH{ "(topic of first search)" format=" * $topic" }%`
156 - Now we nest the searches. We need to escape the second search, e.g. the first search will build a valid second search string:
157 - `%SEARCH{ "freedom" format=" * $topic: $n$percntSEARCH{ \"$topic\" format=\" * $dollartopic" }$nop%\" }%`
159 Note that we escape the second search so that it does not get evaluated by the first search:
161 - `$percnt` to escape the leading percent of the second search
162 - `\"` to escape the qouble quotes
163 - `$dollar` to escape the `$` of `$topic`
164 - `$nop` to escape the `}%` sequence
