Add to [[MainMenu]]:
----------------
<html><a href="javascript:;" onclick="
var t=prompt('Enter search text',''); if (!t) return;
config.extensions.customSearchValue=t;
story.displayTiddler(null,'BringForwardList');
story.refreshTiddler('BringForwardList',null,true);
">BringForwardList</a></html>
----------------
This creates a link that, when clicked, prompts for input. If non-blank
input is entered, the value is then stored internally in
"config.extensions" (a 'holding bin' provided by the TWCore to keep any
extra variables created by customizations). Calls to
story.displayTiddler() and story.refreshTiddler() ensure that the
"BringForwardList" tiddler is opened in the story column, and that it's
contents are up-to-date.
Then, create [[BringForwardList]], containing:
----------------
Search results for: "<<message extensions.customSearchValue>>"
<<forEachTiddler
where 'tiddler.text.contains(config.extensions.customSearchValue)'
write '"* [["+tiddler.title+"]]\n"'
>>
----------------
The <<message>> macro is used to *display* the search text above the
results, followed by the <<forEachTiddler>> macro, using the stored search
text in the "where" clause. For this example, I used a simple "write"
clause that just outputs the matched tiddler titles as bulleted links.
That should do it. Let me know how it goes...
enjoy,
