The schema is composed of 3 pieces of data, which are the parameters for the
- A unique identifier for the given data, such as a primary key
- A title that will be used to generate a searchable index
- Any data you wish to associate with an object_id. This data will be returned when searches are performed.
redis-completion uses multiple sorted sets to
perform searches for partial phrases. When indexing a term, it is split up into
pieces of increasing length, so “test” becomes
[te, tes, test]. Each of these
partial phrases becomes the key to a sorted set. Each sorted set contains the IDs
of data that matched that particular phrase. After finding the IDs, the associated
data is pulled from a hash keyed by
the object’s id.
