Using Inverse Operators for Queries |
| 摘要 |
In one embodiment, a method includes receiving, from a client system of a first user, a query comprising one or more n-grams, parsing the one or more n-grams of the query to identify a first query constraint and one or more second query constraints, wherein the first query constraint has been previously flagged as identifying greater than a threshold number of objects, generating a query command based on the query, wherein the query command comprises an inverse constraint associated with the first query constraint and the one or more second query constraints, and generating one or more search results based on the query command, each search result corresponding to an object of a plurality of objects. |
