Filtering Results

Basic Filtering

To narrow down results, use the options on the Analyze or Refine tabs on the left-hand toolbar. Available options depend on whether you've searched for references, substances, or reactions.

Use the Analyze tab to choose from a category's most common results in your answer set, such as author name, journal name, or publication year.

Use the Refine tab to search for any value or range in a category, such as publication years, document types, or languages. Refine acts more like the search filters you're probably used to: different options eliminate results that do not match your criteria.

         


Common Refinements

The Analysis and Refine options will be different based on what kind of search you've conducted: Reference, Substances, or Reactions. Listed below are some commonly-used options to narrow your search down:

Reference

  • Author Name (Analyze, Refine): Search by, or select only references by, a particular author.
  • CAS Registry Number (Analyze): Select only references including a certain substance (identified by registry number).
  • Document Type (Analyze, Refine): Select only certain types of references (such as journal article, patent, review article). Note: Use Refine to select multiple types.
  • Index Term (Analyze): Select references indexed using certain descriptive terms.
  • CA Concept Heading (Analyze):  Select only references with certain terms indicated as main concepts.
  • Language (Analyze, Refine): Select only references in a certain language. Note: Use Refine to select multiple languages.
  • Publication Year (Analyze, Refine): Select references from a certain year or years. Note: Use Refine to choose a range of years (including a year to present) and Analysis to see during which years the most references were published.
  • Research Topic (Refine): Modify your search by adding more terms.

Substances

  • Atom Attachment (Refine): Select an attachment site and limit to the atom(s) you would like to see.
  • Chemical Structure (Refine): Modify your search in the structure editor or add limits (such as only substances that have references).
  • Commercial Availability (Analyze, Refine): Select only substances available or not available commercially.
  • Elements (Analyze): Select only substances that include a certain element.
  • Isotope-Containing (Refine): Select only substances that do or do not contain isotopes.
  • Reaction Availability (Analyze): Select only substances that are or are not referenced in a reaction.
  • Reference Availability (Refine): Select only substances that do or do not have references attached.
  • Substance Role (Analyze): Select only substances used in a role in their references (such as Preparation or Uses).

Reactions

  • Author Name (Analyze, Refine): Search by, or select only references by, a particular author.
  • Catalyst (Analyze): Select only reactions using a certain catalyst.
  • Document Type (Analyze, Refine): Select only certain types of references (such as journal article, patent, review article). Note: Use Refine to select multiple types.
  • Excluding Reaction Classification (Refine):  Select only reactions without certain classifications (such as biotransformation, electrochemical, and non-catalyzed).
  • Experimental Procedure (Analyze): Select only reactions that do or do not have an attached experimental procedure.
  • Language (Analyze): Select only references in a certain language.
  • Number of Steps (Analyze, Refine): Select only reactions that take a certain number of steps. Note: Use Refine to choose a number range.
  • Product Yield (Analyze, Refine): Select only reactions with a certain percentage product yield. Note: Use Refine to choose an upper and/or lower limit and Analysis to select ten-percent ranges.
  • Publication Year (Analyze): Select only reactions from a certain year.
  • Reaction Classification (Refine): Select only reactions with certain classifications (such as biotransformation, electrochemical, and non-catalyzed).
  • Reaction Structure (Refine): Modify your search in the reaction editor.
  • Solvent (Analyze): Select only reactions using a certain catalyst.  

Going from References to Reactions to Substances

Once you've searched for a reaction, a substance, or references, it's easy to look up either of the other two areas based on your results. Next to the name of the search, look for the Get References, Get Substances, or Get Reactions icons:

Before selecting a button, select the checkboxes next to the results for which you want to see reactions, substances, or references. If you don't select any, you can find them for all results; however, this may go over the 10,000 result limit. After choosing your results, select Get References, Get Reactions, or Get Substances. Depending on which option you choose, you'll be able to select options such as reaction role of the substance:
