Support additional string/primitive query values

[jsejcksn]

• true
• false
• null
• "true"
• "false"
• "null"

These are all valid JSON values, but can't all be queried at present. Right now, true and false are being cast to their primitive types when supplied as string queries (and null is not):

q=booleanField1:true,booleanField2:false

jsonbox/src/helper.js

Lines 84 to 85 in 6781bd2

	if (value == 'true') query['data.' + key] = true;
	else if (value == 'false') query['data.' + key] = false;

I think it might be better to treat these non-string primitive values the way that numbers are being treated, but as special cases:

q=booleanField1:=true,booleanField2:=false,fieldWithNoValue:=null

jsonbox/src/helper.js

Line 71 in 6781bd2

else if (value.startsWith('=')) query['data.' + key] = +val;

I haven't worked with mongo in a long time, so I'm not sure about the exact syntax, but something like

else if (value.startsWith('=')) {
  if (val === 'true') query['data.' + key] = true;
  else if (val === 'false') query['data.' + key] = false;
  else if (val === 'null') query['data.' + key] = null;
  else query['data.' + key] = +val;
}

and then you could just remove the code from lines 84–85 above.

I think you might be able to implement the conditional primitive matching now, without breaking changes, but allowing for string matching of "true" and "false" would be a breaking change for the next major version.
