FILTERING LISTVIEWS WITH URL QUERY STRING

• Basic URL filters - AllItems.aspx?FilterFields1=ColumnName&FilterValues1=ValueText
• Filtering multiple columns - AllItems.aspx?FilterFields1=ColumnName&FilterValues1=ValueText&FilterFields2=ColumnName&FilterValues2=ValueText
• Multiple filter values on a single column -&FilterName=______&FilterMultiValue=____;____;_____
• Wildcard filters - &FilterName=Product&FilterMultiValue=*jet* // for all values that contains "jet".
• Filtering on lookup columns - AllItems.aspx?FilterFields1=Product&FilterValues1=4 // where Product is a Lookup Column and '4' is the Lookup Id of the text you want to filter.
