string in int field -> 0

[baxiry]

Comparison operators : $gt $lt $gte $lte and $eq handle any string as 0, for example :
filter:{age: {$gte: 'adam'}}

adam her is equal 0,

great then , less then is

see #5

now just $eq $ne are work with string.
every thing else will not work with. it will return : nothing match result
