vsts - Query items user was mentioned in -

is there way query work items user mentioned? able receive 'hard-coded' results querying for

"history"-"contains word"-"\@username",

but want generic version, works users. (opposed writing 1 query every user)

you can’t achieve through work item query directly, build app retrieve data through rest api (https://www.visualstudio.com/en-us/docs/integrate/api/wit/wiql), change query text according different conditions (e.g. users)
