	3	+In this section, we will go throw an XSL function to get trackings by trkID or using Keys/Values.
	4	+
	5	+= Parameters =
	6	+
	7	+GetTracking uses 4 params to help retrieve trackings in question.
	8	+
	9	+1. xpathExpression: read the IXpathExpression for more details ([[IXpathExpression>>https://ixpath.app/xwiki/bin/view/iXPath%20V3/IXpathExpression/]])
	10	+1. limit: it defines the max number of tracking to retrieve. **it's optional. **(Optional)
	11	+1. order: whether you want to order the list of trackings in a descending way or not by a certain key order. The default value is 'trkID' and it's optional as long as you fill in the limit value. (Optional)
	12	+1. projection: you can return only some wanted fields instead of fetching the integrity of tracking object. (Optional)
	13	+
	14	+= Uses =
	15	+
	16	+We suppose that we have a tracking type named Product. It has 3 data (Name, Brand, and Country).
	17	+
	18	+if we want to get Product by key values
	19	+
	20	+ {{code language="XML"}}<xsl:value-of select="ixf:GetTracking('Product [Name == Laptop AND Brand == Dell AND _statusTracking==Delivered ]')"></xsl:value-of>{{/code}}
	21	+
	22	+Searching by trkIDs :
	23	+
	24	+{{code language="XML"}}
	25	+<xsl:value-of select="ixf:GetTracking('Product [ _trkID in '632061bef8aef457701a28d2;632061e5f8aef457701a28d3;63206213f8aef457701a28d4]')"></xsl:value-of>
	26	+{{/code}}
	27	+
	28	+Set the limit value to get only 4 elements  :
	29	+
	30	+{{code language="XML"}}
	31	+<xsl:value-of select="ixf:GetTracking('Product [Name == Laptop AND Brand == Dell AND _statusTracking==Delivered ]',4)"></xsl:value-of>
	32	+{{/code}}
	33	+
	34	+Add an order by Country :
	35	+
	36	+{{code language="XML"}}
	37	+<xsl:value-of select="ixf:GetTracking('Product [Name == Laptop AND Brand == Dell AND _statusTracking==Delivered ]',4,'Country')"></xsl:value-of>
	38	+{{/code}}
	39	+
	40	+if you want to add an order without filling the limit, you must put 0 as a value to it :
	41	+
	42	+{{code language="XML"}}
	43	+<xsl:value-of select="ixf:GetTracking('Product [Name == Laptop AND Brand == Dell AND _statusTracking==Delivered ]',0,'Country')"></xsl:value-of>
