Metadata Search Guidelines
To search for rules that use the 
		  metadata keyword, select the 
		  metadata keyword on the rules Search page and,
		  optionally, type any portion of the metadata. For example, you can type: 
		
-  
			 searchto display all rules where you have usedsearchfor key .
-  
			 search httpto display all rules where you have usedsearchfor key andhttpfor value .
-  
			 author snortguruto display all rules where you have usedauthorfor key andSnortGurufor value .
-  
			 author sto display all rules where you have usedauthorfor key and any terms such asSnortGuruorSnortUser1orSnortUser2for value .TipWhen you search for both key and value , use the same connecting operator (equal to [ =] or a space character) in searches that is used in the key value argument in the rule; searches return different results depending on whether you follow key with equal to (=) or a space character.
Note that regardless of the format you use to add metadata, the
		  system interprets your metadata search term as all or part of a 
		  key value  or 
		  key =value  argument. For example, the following would
		  be valid metadata that does not follow a 
		  key value  or 
		  key =value  format: 
		
ab cd ef gh
However, the system would interpret each space in the example as a separator between a key and value . Thus, you could successfully locate a rule containing the example metadata using any of the following searches for juxtaposed and single terms:
cd ef
ef gh
ef
but you would not locate the rule using the following search, which the system would interpret as a single key value argument:
ab ef
