Combining Reference Search with Structures or Reactions
You may run into the following issues and here is how to resolve them:
Search comes back with too many results
Remember that SFn has different search algorithm. Classic SF uses indexed terms to find results. SFn uses indexed terms, but also uses the Title, Abstract, Keywords to find documents that are referring to the query entered, that might have been missed in Classic SF. The relevancy should place higher importance on those documents that have more hits as well as hits on Concepts and Substances.
To narrow the search results:
Searches on "C O2" vs "CO2" give different results
Molecular formulas should be searched on the Substance Advanced Search page. There is a specific field that will search Molecular Formulas only to provide the correct match. If there is a need for references on a specific chemical find the chemical and do a crossover to References for the substance(s). Then leverage the Search within on the Reference page to find the specific details within those documents.
Search for the specific journal yields different results in SF and SFn
CAS is still working on how Journals and Organizations are searched in SFn. Coming soon CAS will be associating all the related Journals to each other so that we can search one and retrieve all the different entries. As for now:
