--- title: "Discover points" method: POST path: "/collections/{collection_name}/points/discover" tags: ["Search"] deprecated: true --- # Discover points `POST /collections/{collection_name}/points/discover` > **Deprecated.** Use context and a target to find the most similar points to the target, constrained by the context. When using only the context (without a target), a special search - called context search - is performed where pairs of points are used to generate a loss that guides the search towards the zone where most positive examples overlap. This means that the score minimizes the scenario of finding a point closer to a negative than to a positive part of a pair. Since the score of a context relates to loss, the maximum score a point can get is 0.0, and it becomes normal that many points can have a score of 0.0. When using target (with or without context), the score behaves a little different: The integer part of the score represents the rank with respect to the context, while the decimal part of the score relates to the distance to the target. The context part of the score for each pair is calculated +1 if the point is closer to a positive than to a negative part of a pair, and -1 otherwise. ## Path parameters - `collection_name` string, required ## Query parameters - `consistency` union — Read consistency parameter Defines how many replicas should be queried to get the result * `N` - send N random request and return points, which present on all of them * `majority` - send N/2+1 random request and return points, which present on all of them * `quorum` - send requests to all nodes and return points which present on majority of them * `all` - send requests to all nodes and return points which present on all of them Default value is `Factor(1)` - integer - 'majority' | 'quorum' | 'all' — * `majority` - send N/2+1 random request and return points, which present on all of them * `quorum` - send requests to all nodes and return points which present on majority of nodes * `all` - send requests to all nodes and return points which present on all nodes - `timeout` integer ## Request body - DiscoverRequest — Use context and a target to find the most similar points, constrained by the context. - `shard_key` union — Specify in which shards to look for the points, if not specified - look in all shards - union - union - string - integer - ShardKey[] - union - string - integer - ShardKeyWithFallback - `target` union, required - string - integer - `fallback` union, required - string - integer - unknown - `target` union — Look for vectors closest to this. When using the target (with or without context), the integer part of the score represents the rank with respect to the context, while the decimal part of the score relates to the distance to the target. - union - union — Type, used for specifying point ID in user interface - integer - string, uuid - number[] - SparseVector — Sparse vector structure - `indices` integer[], required — Indices must be unique - `values` number[], required — Values and indices must be the same length - unknown - `context` ContextExamplePair[], nullable — Pairs of { positive, negative } examples to constrain the search. When using only the context (without a target), a special search - called context search - is performed where pairs of points are used to generate a loss that guides the search towards the zone where most positive examples overlap. This means that the score minimizes the scenario of finding a point closer to a negative than to a positive part of a pair. Since the score of a context relates to loss, the maximum score a point can get is 0.0, and it becomes normal that many points can have a score of 0.0. For discovery search (when including a target), the context part of the score for each pair is calculated +1 if the point is closer to a positive than to a negative part of a pair, and -1 otherwise. -

Defines how many extra vectors should be pre-selected using quantized index, and then re-scored using original vectors. For example, if `oversampling` is 2.4 and `limit` is 100, then 240 vectors will be pre-selected using quantized index, and then top-100 will be returned after re-scoring. - unknown - `indexed_only` boolean — If enabled, the engine will only perform search among indexed or small segments.

If estimated filters selectivity is higher than this value, ACORN will not be used. Selectivity is estimated as: `estimated number of points satisfying the filters / total number of points`. 0.0 for never, 1.0 for always. Default is 0.4. - unknown - unknown - `limit` integer, required — Max number of result to return - `offset` integer, nullable — Offset of the first result to return. May be used to paginate results.
