Would appreciate help with custom search

[Magnus]

1)

I get an error Internal javascript error when clicking any of two radio-button (I think) if the state-tiddler $:/state/customSearch where I store the state does not exist, how can I create the state-tiddler in the radio-button if it does not exist?

2)

In the custom search I use the 

<$list filter="[rank[species]search:caption{$:/state/customSearch}contains:summer_light{$:/state/customSearch!!summer_light_search}sort[caption]">//<$link to={{!!title}}><$view field="caption"/></$link>//<br></$list>

to search for all tiddler with the field value specified in the state-tiddler, but if the state-tiddler field is empty nothing is shown, I would like to see all tiddler regardless of the value in the target-tiddlers fields, how can I go about to do that?

I have a demo at http://magnus.playground.tiddlyspot.com/#content%2Fsearch:content%2Fsearch%20content%2Fsearch%2Fall%20content%2Fsearch%2Fabbreviations%20content%2Fsearch%2Fauctor%20content%2Fsearch%2Ffavorites

There's a syntax error here -- needs to end ...sort[caption]]

Are you saying that if the search doesn't find anything then you want to see ALL tiddlers? You could use the ~ ELSE clause to put

a fallback filter expression that shows all tiddlers in the event that the first run doesn't match any. See:
