 ### Examples
 
 **The $exists operator will look for values that do or do not exist:**
-{ secret: { $exists: true} 
-{ secret: { $exists: false} 
+    @{ secret: { $exists: true} 
+    @{ secret: { $exists: false} 
 
 **The $eq and $ne operator will look for values match or do not match a value:**
-@{ gender: { $ne: "male" } }
-@{ name: { $eq: "kerri" } }
+    @{ gender: { $ne: "male" } }
+    @{ name: { $eq: "kerri" } }
 
 **The $in operator will look for equal values that match anything specified in an array:**
-@{ rank: { $in: [ "warrior", "scholar", "sage" ] } }
+    @{ rank: { $in: [ "warrior", "scholar", "sage" ] } }
 
 **The $nin operator will look for equal values that do NOT match anything in an array:**
-@{ rank: { $nin: [ "novice", "precept", "learner" ] } }
+    @{ rank: { $nin: [ "novice", "precept", "learner" ] } }
 
 **The $all operator for matching all the elements in an array for a specified field:**
-{ items: { $all: [ "bread", "nut butter", "jam" ] } }
+    @{ items: { $all: [ "bread", "nut butter", "jam" ] } }
 
 **The $elemMatch operator for matching ANY element in an array for a specified field:**
-{ items: { $elemMatch: { "crowbar", "key", "spell", "explosive" } } }
+    @{ items: { $elemMatch: { "crowbar", "key", "spell", "explosive" } } }
 
 **The $and operator logically combines two or more queries:**
-{ $and: [ { age: { $gt: 12 } }, { age: { $exists: true } } ] }
+    @{ $and: [ { age: { $gt: 12 } }, { age: { $exists: true } } ] }
 
 **The $or operator logically combines two or more queries:**
-{ $or: [ { age: { $gt: 12 } }, { age: { $exists: false } } ] }
+    @{ $or: [ { age: { $gt: 12 } }, { age: { $exists: false } } ] }
 
 **The $nor operator logically combines two or more queries:**
-{ $nor: [ { age: { $lt: 12 } }, { age: { $exists: false } } ] }
+    @{ $nor: [ { age: { $lt: 12 } }, { age: { $exists: false } } ] }

 **Search by regular expression:**
-@{ $name: { $regex: /^M.*/}}
+    @{ $name: { $regex: /^M.*/}}
 
 **Regex options: case insensitive:**
-@{ $name: { $regex: /^jan.*/, $options: "i"}}
+    @{ $name: { $regex: /^jan.*/, $options: "i"}}
 
 **Find by elements in array:**
 This matches documents that contain all of these array elements:
-@{ $skills: { $all: }}
+    @{ $skills: { $all: }}
 
 **Match on any element in the array:**
-@{ $skills: "negotiation"}
+    @{ $skills: "negotiation"}
 
 **Match on inequality:**
-@{ $strength: { $gt: 18 } }
+    @{ $strength: { $gt: 18 } }
