Linq query builder control in html [closed]

My application is built in blazor. Looking to allow business users type filter expression which are simple linq query like.

For example say my graph is Patient and Address. So I expect a user to type expressions likePatient.Name = ‘John’ and Patient.Adddress.Street = ‘Main*’ and Patient.Age > 30

I have tried to build a smart textbox with autocomplete that evaluates each keystroke and then refreshes the options but there are so many scenarios to handle. I just wonder if anyone has already built something like this and can offer pointers.

Thanks
