Search Limits Significantly Expanded Exclusively in STNext

07. March 2019

Effective immediately, search limits have been significantly and exclusively expanded in STNext®. You can now have up to 100 million answers per file per session in all databases on STNext.

In addition, the structure searchable databases CAS RegistrySM, MARPAT® and CASREACT® now allow up to 100 million iterations per search.

These increases reduce the need to run sample searches in the CAS structure searchable databases, especially for customers with STN Global Value pricing plans. Customers may still want to run sample searches before proceeding to FULL searches, as a means to check their structures.

HELP LIMITS, as well as HELP SLIMITS in CAS REGISTRY, MARPAT and CASREACT, have been updated to reflect the newly expanded limits.
