	separated by spaces (e.g. 'wyz Max*' in Name will list both users named\n

	negation, e.g. '~alfiest' in comments will restrict the search to users\n
	that do not have 'alfiest' in their comments).<br /><br />\n
    The Ratio field accepts 'Inf' and '---' besides the usual numeric values.<br /><br />\n
	The subnet mask may be entered either in dotted decimal or CIDR notation\n
	(e.g. 255.255.255.0 is the same as /24).<br /><br />\n
    Uploaded and Downloaded should be entered in GB.<br /><br />\n
	For search parameters with multiple text fields the second will be\n
	ignored unless relevant for the type of search chosen. <br /><br />\n
	'Active only' restricts the search to users currently leeching or seeding,\n
	'Disabled IPs' to those whose IPs also show up in disabled accounts.<br /><br />\n
	The 'p' columns in the results show partial stats, that is, those\n
	of the torrents in progress. <br /><br />\n
	The History column lists the number of forum posts and torrent comments,\n
