The reason is you have both part empty so both part returns the whole list
of tiddlers and negative sign cause all-all = nothing
1. create those temp tiddler
2. put something in them
3. run the code
4. now empty the negsearch tiddler
5. run again
6. it works
Your mistake is here you think if you put Mark and Mathew like
Mark Mathew
Then your search will find tiddlers has Mark OR Mathew, but your code
search for composition "Mark Mathew"
Furthermore if you use [search[]] TW returns all tiddlers! When you have
empty negsearch you return all tiddlers.
Use list field or first convert your text to a list of tiddlers.
