TWiki Formatted Search Results

Inline search feature allows flexible formatting of search result

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 parameters can be used to specify a customized search result:

1. header="..." parameter

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.
Example: header="| *Topic:* | *Summary:* |"

2. format="..." parameter

Use the format parameter to specify the format of one search hit.
Example: format="| $topic | $summary |"

Variables that can be used in the format string:

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.

Examples

Nested Search

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.

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).

• First search:
  • %SEARCH{ "culture" format="   * $topic is referenced by: (list all references)" nosearch="on" nototal="on" }%
• Second search. For each hit we want this search:
  • %SEARCH{ "(topic found in first search)" format="   $topic" nosearch="on" nototal="on" }%
• 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:
  • Use $percnt to escape the leading percent of the second search
  • Use \" to escape the double quotes
  • Use $dollar to escape the $ of $topic
  • Use $nop to escape the }% sequence

Write this:

%SEARCH{ "culture" format="   * $topic is referenced by:$n      * $percntSEARCH{ \"$topic\" format=\"   $dollartopic\" nosearch=\"on\" nototal=\"on\" }$nop%" nosearch="on" nototal="on" }%
