Numeric search fields

Compendex and Inspec records contain standardized numeric quantities and ranges. This normalized format of data improves numeric search functionality in Engineering Village.

Use the Expert search form to perform specific numeric searches in Compendex and Inspec.

You may also refine your numeric search results using the Numeric filter feature on the Quick and Expert search result pages. The Numeric filter is an easy way to construct a numeric search that does not require the use of field names and Boolean logic.

Conduct numeric search

You can specify which numeric field(s) you want to include in your search queries. Below are the field names, applicable databases, data types, default units, and descriptions for each of the 62 numerically indexed fields.

Refer to Numeric search queries for detailed instructions regarding the search syntax to run numeric search queries on the Expert search page in Compendex and Inspec.

Additionally, you may refer to Numeric search optional units for a comprehensive list of all the optional units of measure that you may use to conduct numeric search queries on the Expert search page for Compendex and Inspec.

Note Each field name contains an "NU" (Numeric) prefix.
