Search based on FormTiddlerPlugin data field

[Noltdude]

I am using ForEachTiddlerPlugin, DataTiddlerPlugin, FormTiddlerPlugin
attempting to perform a search based on a FormTiddlerPlugin data
field. For example, I would like to have an input field with a button
"search flavor", I type in "chocolate" and it only looks in the
FormTiddler datafield "flavor", not the entire tiddler content. Has
anyone done something like this?

I'm not very familiar with the FormTiddlersPlugin, but I assume it
simply uses extended fields. In that case, you could use
tiddler.fields[], like so:
---------------
<<forEachTiddler
where 'tiddler.fields["flavor"] == "tasty"'
write 'tiddler.title'
>>
---------------

Another thread with a script making use of FET and extended fields:

FormTiddlersPlugin and DataTiddlerPlugin pre-date the existence of
TW's custom tiddler fields, so your assumption is incorrect. Instead
of using tiddler fields, data is embedded directly into the tiddler
body text, in between <data>...</data> markers, and uses the following
plugin-defined functions to set/access the stored values:
DataTiddler.setData(tiddler, field, value, default)
DataTiddler.getData(tiddler, field, default)
DataTiddler.getDataObject(tiddler)
DataTiddler.getDataText(tiddler)

I have something that does what your looking for, except it uses
custom fields, but figure it might give you some help:

<<forEachTiddler where 'tiddler.tags.contains("Training") &&
store.getValue(tiddler,"assignedto") &&
(store.getValue(tiddler,"assignedto").readBracketedList().contains(store.getValue(context.inTiddler,"searchfield")))'
sortBy
'store.getValue(tiddler,"traindate")'
write '"|"+store.getValue(tiddler,"assignedto")
+"|"+store.getValue(tiddler,"traindate")+" |[["+tiddler.title+"]]|\n"'
>>

Then I have this in my EditTemplate:
<div macro="showWhen tiddler.tags.contains('search')">
<br />
<strong>Look for: </strong>&nbsp;<span macro='edit searchfield'> </
span>
<br />
</div>

and this in my ViewTemplate:
<div macro="showWhen tiddler.tags.contains('search')">
<br />
<strong>Look for: </strong> <span macro='view searchfield'> </span>
<br />
</div>

It allows me to find all tiddlers tagged 'Training' that have the same
name in the 'assignedto' field as I put in this tiddlers custom
'search' field.
