package bleve
// An IndexAlias is a wrapper around one or more
// Index objects. It has two distinct modes of
// operation.
// 1. When it points to a single index, ALL index
// operations are valid and will be passed through
// to the underlying index.
// 2. When it points to more than one index, the only
// valid operation is Search. In this case the
// search will be performed across all the
// underlying indexes and the results merged.
// Calls to Add/Remove/Swap the underlying indexes
// are atomic, so you can safely change the
// underlying Index objects while other components
// are performing operations.
