Advanced Search: Searching the Numerical Data Field

The Numerical Data Indexing field contains structured numeric data in whatever units are appropriate to the quantities described.

To search the Numerical Data field, preface each value with a numerical data field tag and a symbol indicating the relationship between the value in your query and the value or range of values in the retrieved records.

Definition
= equal to

<

 less than

>

 greater than

<=

 less than or equal to

>=

 greater than or equal to

:

 in the range defined by the values to the left and the right of the symbol

Examples

TE=1.0E+02 searches for a temperature value equal to 1.0E+02. This search will also retrieve a range of values if 1.0E+02 falls within the range.

TE>1.0E+02 searches for a temperature value greater than 1.0E+02. This search will also retrieve records with a range of values if any value in the range is greater than 1.0E+02.

TE=1.0E+02:2.0E+03 searches for a temperature value in the range of 1.0E+02 and 2.0E+03 inclusive. This search will also retrieve a range of values, as long as any one of the values in the range falls within the range of values in the search query. This is equivalent to a range search on the Search page.

TE>=1.0E+02 AND TE<=2.0E+03 searches for a temperature value greater than or equal to 1.0E+02 and a value less than or equal to 2.0E+03 in the same record.
