Top Tips for Experienced STN Searchers
General
n
n
All project components are automatically “saved” for future
use. When you sign in, you can continue working where
you left off. System inactivity timeout is set for 40 minutes.
n
The maximum number of L-numbers for one project
is 9,999 with essentially no limit to the number of total
answers.
n
Answers can be exported in a zipped .docx, XML or
BizInt Smart Charts format.
n
The command for Search is implied. Do not precede any
query statement with “S”.
Text
n
Use an asterisk (*) for truncation instead of a question
mark (?). The exclamation point (!) and hash (#) symbols
are still valid. Truncation symbols may be used in any
combination.
n
Use the question mark (?) outside the Query panel for a
list of keyboard shortcuts.
n
Use the Settings to control Cross File searching, spellings,
plurals, abbreviations and other enhancements for search
terms, as well as display and patent family table settings.
n
Enable the Cross File Search option, click Get References,
or manually enter a Cross File search operator to retrieve
substance records pertaining to reference documents.
The manual Cross File Search operator SUBX is used to
find substances from a bibliographic search, e.g. (SUBX
US2008-100562/AP) or SUBX L3.
n
There are no stop words in new STN.
n
The (U) relational proximity operator restricts the
occurrence of search terms to the same entity or across
associated fields. In general, the (U) operator replaces the
(L) operator.
n
Date searches require four digit years (e.g., YYYYMMDD
or YYYY).
n
Patent classification code fields are up-posted for
automatic retrieval of corresponding sub-codes
(A23G0001/IPC is searched as A23G0001*/IPC).

New STN accepts Unicode characters in search queries,
so non-Latin characters can be searched, e.g. Greek
symbols, Chinese, Japanese, etc.
Substance & Structure
n
There is no Basic Index in substance files. All substance
queries in CAS REGISTRYSM and Derwent Chemistry
Resource (DCR) need to be searched with a valid field
code, e.g. 50-00-0/RN or CAFFEINE/CN.
n
For chemical name segment searching, only natural name
segments broken at spaces and punctuation are used,
e.g., (PYRROLE (U) ##CARBOXAMIDE (U) *FLUORO*)/
CNS.
n
Enable the Cross File Search option, click Get References,
or manually enter a Cross File search operator to retrieve
reference documents pertaining to substance records.
The manual Cross File Search operator REFX is used to
find references to a substance search, e.g. (REFX STR1/
SSS,FULL) or REFX L1 or (REFX CAFFEINE/CN).
n
Link roles and keywords to a substance search with the (U)
operator, e.g., (REFX L1) (U) PREP/RL (U) (*BACTERIA*
OR *BIOTIC*)/IT, where L1 is a search in CAS REGISTRY,
or use the Get References button to add a super role.
n
Atom, Bond and Variable Attributes are available.
Right-click a node or bond in the Structure Editor.
n
The Lock Rings tool blocks rings and chains from further
ring fusion. Select the tool and click a chain to toggle all
bonds and nodes between Chain and Ring/Chain.
n
The Lock Atoms tool blocks further substitution on nodes.
n
Structure queries (.str) created in STN Express® or STN®
on the WebSM are not compatible with the new STN search
platform. Saved structures can be imported into the
structure editor from .cxf and .mol formats or directly input
via CAS Registry Number® identifier, InChI or SMILES.
n
EXACT scope is more narrowly defined in new STN,
excluding Incompletely Defined Substances.
