Steps to replicate the issue (include links if applicable):
In the Wikidata Query Service (https://query.wikidata.org/), If you want to negate a predicate (e.g. "!wdt:P31" for "not instance of") or reverse a predicate (e.g. "^wdt:P921" for "is main subject of") then autocomplete does not work.
- take a SELECT {} template
- start a query
- type "^wdt:instan" and try to autocomplete
What happens?:
What happens is that it reports it does not know the "^wdt" namespace.
What should have happened instead?:
It should be aware of the ! and ^ modifiers and remove that in the namespace lookup.
