'Filter Projections' not support int ?

[iyaozhen]

code:

from jmespath import search
test = {
    'data': {
        'fields': [
            {
                'class_id': 100,
                'orders': [1, 2, 3]
            },
            {
                'class_id': 200,
                'orders': [3, 2, 1]
            }
        ]
    }
}
print search("data.fields[?class_id=='100'].orders", test)
[]

debug:

print search("data.fields[?class_id==100].orders", test)

jmespath.exceptions.ParseError: invalid token: Parse error at column 23, token "100" (NUMBER), for expression:
"data.fields[?class_id==100].orders"

Must be that:

from jmespath import search
test = {
    'data': {
        'fields': [
            {
                'class_id': '100',
                'orders': [1, 2, 3]
            },
            {
                'class_id': 200,
                'orders': [3, 2, 1]
            }
        ]
    }
}
print search("data.fields[?class_id=='100'].orders", test)
[[1, 2, 3]]

It is like same bug with #132

If you look in the examples you will see that in order to filter by a number, the number must be surrounded by "back ticks"

search("data.fields[?class_id == `200`].orders",test)

That worked for me.

@AnalyticsSupplyLLC Thx, my mistake

This was super helpful for me. Is the need for backticks explicitly stated somewhere, besides the implicit usage in the examples and the grammar spec? If not, I'd be happy to make a PR with an update to the documentation; it would be helpful to know if I'm overlooking something.
