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.
Claims21
A method, comprising:
- in response to a search request including first and second logically related criteria, determining, via a processor, 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, via the processor, 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, via the processor, the second criterion as the basis for the generating of the subset of the records of the database;
- and
- searching the subset of the records.
A tangible computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
- in response to a search request including first and second logically related criteria, determine 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, select 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, select the second criterion as the basis for the generating of the subset of the records of the database;
- and
- search the subset of the records.
An apparatus, comprising:
- a statistics obtainer to, in response to a search request including first and second logically related criteria, determine 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;
- a driving criterion selector to:
- when the first number is less than the second number, select the first criterion as a basis for generating a subset of the records of the database;
- and
- when the second number is less than the first number, select the second criterion as the basis for the generating of the subset of the records of the database;
- and
- an analyzer to search the subset of the records, wherein at least one of the statistics obtainer, the driving criterion selector, or the analyzer is implemented via a processor.
