Due to recent investments in STNext's retrieval infrastructure, users of the Derwent World Patents Index (DWPI) on STNext are now experiencing better performance when searching WPINDEX/WPIDS/WPIX.

Since the beginning of February 2024, searches and analyses of patent results are significantly faster. Of special note, search queries with numerous search terms and proximity operators are running much faster than before.

Also, users now need less time for processing multifile search results, e.g., duplicate removal between CAplusSM and DWPI answer sets with the TRANSFER and DUPLICATE commands.
