Description

We could add the onear value to the possible parsing grammars of userInput().

This would allow to parse the user input as a query such that the terms are combined by the onear() operator.

Research direction
Examine the existing implementation of userInput() grammar parsing in the Vespa codebase. The issue requests adding the 'onear' value to the set of allowed grammars. Check the documentation at https://docs.vespa.ai/documentation/query language.html#userinput for current grammars and the onear operator. Look at the source code responsible for parsing the grammar argument to understand how new values are integrated. Also review any comments on the issue for additional context. Consider checking if this feature has already been implemented in later versions.
