+### Tag Filters
+The `tags` field supports advanced queries through combining tag names and operators into a list. 
+
+The supported operators are: 
+* `not` 
+* `and`
+* `or`
+
+Input the operators in the following format: `"__$<op>"`. To exclude a tag, you can also use the `-` prefix before the 
+tag name, unless the tag name begins with the dash character (`-`), in which case you can use `"__$not"`. 
+
+The `or`, and `and` operators apply to all tags that follow them until another operator is specified. The `not` operator 
+applies only to the immediately following tag.
+
+The default operator for a query is `or`, unless `and` is placed at the beginning of the query.
