Great Yonik!
Is it possible to have exists() work on multi valued fields too without crashing?

> Add an if() function which will enable conditional function queries.
> The function could be modeled after a spreadsheet if function (e.g:
> IF(test; value1; value2) where:
>     test is or refers to a logical value or expression that returns a logical value (TRUE
or FALSE).
>     value1 is the value that is returned by the function if test yields TRUE.
>     value2 is the value that is returned by the function if test yields FALSE.
> If value2 is omitted it is assumed to be FALSE; if value1 is also omitted it is assumed
to be TRUE.
> Example use:
> if(color=="red"; 100; if(color=="green"; 50; 25))
> This function will check the document field "color", and if it is "red" return 100, if
it is "green" return 50, else return 25.
