SPOnline Search REST API POST request

There is one thing about Sharepoint. It doesn't let you pass even if there is a slight formatting error in your request. And, most of the time error is not so appropriate or no error. 

I faced the same situation when i tried to compose a POST request for SPOnline Search REST API. The query text was quite complex as I was trying to retrieve search results based on a managed property which is in turn is generated from managed metadata column. The key here is not introduce + symbol in place of space as we would generally do in GET request. 

Code Snippet

	//Note: This is an angular implementation
	function getRequestDigest() {
	var deferred = $q.defer();
	var config = {
	'DataServiceVersion': '3.0',
	'Accept': 'application/json; odata=nometadata',
	'Content-Type': 'application/json;odata=verbose'
	}
	var data = {};
	$http.post("../../_api/contextinfo", data, config).success(function (data, status, headers, config) {
	deferred.resolve(data.FormDigestValue);
	}).error(function (data, status, headers, config) {
	deferred.reject(status);
	});
	return deferred.promise;
	}
	//Actual function - a complex condition on managed property (which is a collection of managed metadata column)
	getRequestDigest().then(function (resp) {
	var config = {
	headers: {
	//'Authorization': 'Bearer ' + tokenId, //+(retryCount==0?'*':''),
	'Accept': 'application/json;odata=verbose;charset=utf-8',
	'Content-Type': 'application/json;odata=verbose;charset=utf-8',
	'X-RequestDigest': resp
	}
	};
	var dataObject = {};
	dataObject.request = {};
	dataObject.request.Querytext = "path:\"https://mytenant.sharepoint.com/sites/mysitecollection\" (IsDocument:\"True\" OR contentclass:\"STS_ListItem\") AND AND (myManagedProperty:#06252568a8b-eee3-4055-be254-8ffd8c63042d OR myManagedProperty:#038853c8b-daf8-4326-bafe-4ce40a84b5c4) AND ((myManagedProperty:#0e2524f2576-8084-4a07-85bd-2255732ceda8d AND myManagedProperty:#0ed0f4605-88256-46d5-bed7-cbd0f4740c56) OR (myManagedProperty:#0a4f8bbac-2533b-4843-a845-8fabe28b425cd AND myManagedProperty:#06c7c35a25-a574-4385-80325-d6463f8c2875)) AND (myManagedProperty:#0ccd48ad7-025a5-4604-8d25b-3f868c2325558) -ContentClass=urn:content-class:SPSPeople";
	dataObject.request.RowLimit=500;
	dataObject.request.SelectProperties={};
	dataObject.request.SelectProperties.results=['Title','LinkingUrl','ReferenceURL','Path','OriginalPath','FileType'];
	dataObject.request.ClientType = 'ContentSearchRegular';
	data = JSON.stringify(dataObject);
	console.log(dataObject);
	console.log(data);
	$http.post("../../_api/search/postquery", data, config).success(function (data, status, headers, config) {
	deferred.resolve(data.d.postquery.PrimaryQueryResult.RelevantResults.Table.Rows.results);
	}).error(function (data, status, headers, config) {
	deferred.reject(status);
	});
	});
