Higher System Limits Increase the Power of STN Substance-Based Searching
14. December 2010
Substance searchers on STN now have vastly enhanced searching power due to a recent increase in search limits in the CAS databases. The increased limits provide greater flexibility and efficiency in the substance-search processes.
The iteration and answer limits for CAS REGISTRY structure searching are increasing from
- 2 million to 6 million for online searches
- 3 million to 8 million for batch searches
The current accession number crossover limit from MARPAT to and from the CA/CAplus databases is doubling from 50,000 to 100,000.
The increase in system limits will permit broader REGISTRY structure searches to run to completion, increasing search power and efficiency. Enhanced crossover limits allow increased flexibility as searchers move between key STN data sources.
