TermsAggregationDescriptor .Include function bug

[deviantus]

Hi, when i trying to use .Include function of terms aggregation below exception occurs.

[ArgumentException: An item with the same key has already been added.]

I think the cause of this error, function tries to add dictionay to both includepattern and regexflags with same key which is "pattern"

        [JsonProperty("include")]
        internal IDictionary<string, string> _Include { get; set; }

        public TermsAggregationDescriptor<T> Include(string includePattern, string regexFlags = null)
        {
            this._Include = new Dictionary<string, string> { {"pattern", includePattern}};
            if (!regexFlags.IsNullOrEmpty())
                this._Include.Add("pattern", regexFlags);
            return this;
        }
