Abstract: Methods and apparatus to search datasets are disclosed. An example disclosed method includes receiving a search request having at least two criteria and assigning the criteria to a first group according to a logical relationship between the criteria. The example method further includes determining which of the criteria in the first group is satisfied by a least amount of records in a database based on a plurality of counts, the counts respectively indicative of a number of corresponding records in the database satisfying a respective one of criteria exhibited by the database, and identifying a reduced set of records in the database to be searched, the reduced set of records corresponding to the first or second criteria that is satisfied by the least amount of records in the database, and reducing a search time associated with the search request by searching the reduced set of records from the database.

Abstract: Methods and apparatus to search datasets are disclosed. An example disclosed apparatus includes a grouper to reference statistics associated with a database to identify which criterion of a group of logically related criteria of a search request satisfies fewer ones of records in the database, an identifier to select the identified criterion of the group of logically related criteria as a driving criterion for the group of logically related criteria, a reduced set generator to form a subset of the records of the database based on the driving criterion, and an analyzer to reduce a search time associated with the search request by searching the subset of the records for a non-driving criterion of the group of logically related criteria.

Abstract: Methods and apparatus to search datasets are disclosed. An example disclosed apparatus includes a count generator to generate a plurality of counts, the counts respectively indicative of a number of corresponding records in a database satisfying a respective one of a plurality of criteria present in the database; a grouper to assign first and second criteria of a search request to a first group according to a logical relationship between the first and second criteria; an identifier to determine, via the plurality of counts, which of the first and second criteria in the first group is satisfied by a least amount of records in the database; and a reduced set generator to form a reduced set of records to be searched based on the determined one of the first and second criteria satisfying the least amount of records in the database.

Abstract: Methods and apparatus to search datasets are disclosed. Example methods include in response to a search request including first and second logically related criteria, determining a first number of records in a database satisfying the first criterion and a second number of records in the database satisfying the second criterion; when the first number is less than the second number, selecting the first criterion as a basis for generating a subset of the records of the database; when the second number is less than the first number, selecting the second criterion as the basis for the identification of the subset of the records of the database; and searching the subset of the records.
