Sometimes they call it tagssearch and sometimes tagsearch, so I wasn't sure how to call it in the toolmap. It is this one. http://braintest.tiddlyspot.com/#TagsSearch-Plugin
As for what I want to do: I plan to have a way to enter the title and author of a book, and every new tiddler will have that in the tiddler title, and I will just add the page #. Then I will tag it by a topic, maybe two. So I will quickly create a large number of tiddlers and a large number of tags.So I would like to be able to search or see the tags associated with a book, despite the fact that there is no one central tiddler for the book. So I want to see a list of tags when I add part of the title or author into the search field. That way I see which tags(topics) are associated with that book. Does that make more sense? From your previous answer (and thinking it through) it sounds like maybe it only works for tags when the entire tiddler title is added? I was hoping for more of a regexp type of solution where I can type a snippet.
<$edit-text tiddler="mytitlesearch" size="50" tag="input"/>
<$reveal state="mytitlesearch" type="nomatch" text="">
<<list-links "[search{mytitlesearch}tags[]]">>
</$reveal>
Something like this, then:
...
<$edit-text tiddler="mytitlesearch" size="50" tag="input"/>
<$reveal state="mytitlesearch" type="nomatch" text="">
<$list filter="[search{mytitlesearch}tags[]]" template="$:/core/ui/TagTemplate">
</$list>
</$reveal>
<$edit-text tiddler="mytitlesearch" size="50" tag="input"/>
''Results:''<br/>
<$list filter="[{mytitlesearch}] +[minlength[3]]" emptyMessage="Type at least 3 characters to see results">
<$list filter="[search{mytitlesearch}tags[]]" template="$:/core/ui/TagTemplate">
</$list>
</$list>
