Numerical Data

The Numerical Data indexing field contains structured numeric data in whatever units are appropriate to the quantities described. To search this field:

  1. Select a unit from the list.

  2. Enter a numeric value in the left-hand box to specify a minimum. Enter a value in the right-hand box to specify a maximum. To specify a range of values, enter a value in both boxes.

Note To display this field on the Search page, review the instructions for Add Another Field.

Numerical Data Example

    This search will retrieve records with a value equal to or greater than 5.0E+01 ohm. It will also retrieve records with a range of values if any value in the range is 5.0E+01 or greater.

    This search will retrieve records with a value equal to or less than .00002 (or 2.0E-05) seconds. It will also retrieve records with a range of values if any value in the range is .00002 or less.

    This search will retrieve records with a temperature value between 1.0E+02 kelvin and 2.0E+03 kelvin. It will also retrieve records with a range of values between 1.0E+02 and 2.0E+03 inclusive. Inclusive means that if any value between the minimum and maximum values of the query match any value between the minimum and maximum values in a record, the record will be retrieved.

    To take another example, the query range 100 to 300 would retrieve records containing these ranges:

    • 50 to 159 (because 159 lies within the query range)
    • 300 to 450 (because 300 lies within the query range)
    • 190 to 260 (because both 190 and 260 lie within the query range)

    This search will retrieve records with the exact value 4.0E+01 S/m. It will also retrieve records with a range of values if 4.0E+01 falls within the range.
