 ## Grammar
 
 Goven has a simple syntax that allows for powerful queries.
 
 Fields can be compared using the following operators:
 
-`=`, `!=`, `>=`, `<=`, `<`, `>`, `%` , `#`
-
-The `%` operator allows you to do partial string matching using LIKE.
-
-The `#` operator is IN operator followed by a combination of values disrupted by a non-spaced comma
-ex: `name#"(duckhue01,duckhue02)"`
+`=`, `!=`, `>=`, `<=`, `<`, `>`, `LIKE` , `IN`, `NOT IN`
 
-Multiple queries can be combined using `AND`, `OR`.
-
-Together this means you can build up a query like this:
-
-`model_name=iris AND version>=2.0`
+Example for : 
+LIKE : `name LIKE hh`
+IN : `status IN ("To Do", "In Progress", "Closed")`
+NOT IN : `status NOT IN ("To Do", "In Progress", "Closed")`
 
 More advanced queries can be built up using bracketed expressions:
-
-`(model_name=iris AND version>=2.0) OR artifact_type=TENSORFLOW`
+`(status LIKE home AND (status IN ("To Do", "In Progress", "Closed") AND artifact='')) OR metric > 0.98 OR metric >= 0.98 OR metric != 0.98`
