This property is only used if you enter more than one keyword value. 

If you do, and only want content to appear on the metadata list if all values entered at the KeyWordValue field match its metadata values, enter true. 

If metadata can appear on the list as long as any value defined at the KeyWordValue field matches the selected metadata value for a content item, enter false. 

Example: 

KeyWordValue for Title (assigned for this server control): home; page; company. 

Metadata values for a content item’s Title metadata definition field: software; ektron; company. 

If KeyWordValueMatchAll = true, content does not appear on metadata list because some items do not match. 

If KeyWordValueMatchAll = false, content item appears on metadata list because one item (company) matches.
