Aggregation Expression - $or

Function Build

Build $or with the Or function from the aggregation package.

// bson.D{bson.E{Key:"visible", Value:bson.D{bson.E{Key:"$or", Value:[]interface {}{"$isPublic", "$isOwner"}}}}}
result := aggregation.Or("visible", "$isPublic", "$isOwner")

Method Build (Builder)

Build $or with the Or method from aggregation.NewBuilder().

// bson.D{bson.E{Key:"visible", Value:bson.D{bson.E{Key:"$or", Value:[]interface {}{"$isPublic", "$isOwner"}}}}}
result := aggregation.NewBuilder().
    Or("visible", "$isPublic", "$isOwner").
    Build()

Build Without Key

When an expression needs to be passed as an argument to another expression, use a WithoutKey variant to build an expression fragment without an output field name.

OrWithoutKey

Function build:

// bson.D{bson.E{Key:"$or", Value:[]any{"$isPublic", "$isOwner"}}}
expr := aggregation.OrWithoutKey("$isPublic", "$isOwner")

Method build (Builder):

// bson.D{bson.E{Key:"$or", Value:[]any{"$isPublic", "$isOwner"}}}
expr := aggregation.NewBuilder().
    OrWithoutKey("$isPublic", "$isOwner").
    Build()
