Filter Behavior:
- Filter by: Displays only those results matching the applied filter(s).
- Exclude: Excludes the results matching the applied filter(s).
The result set changes dynamically as filters are applied or cleared.

Reaction Mapping
Example: Select Mapping Data Available to display the 6 reactions that have atom mapping data.
Reaction Scale
Select a Reaction Scale filter to display reactions using that scale in their method.
Note: Multi-step reactions:
- with different scales across steps will be displayed in multiple bins based on the available scales.
- without scales for some steps will be displayed in the bins based on the available scales for steps.
For example, select Gram to display the 817 reactions that use gram as the scale in their method.
Experimental Protocols
Select an Experimental Protocols filter to display reactions with that information type.
For example, select Synthetic Methods to display the 36 reactions that have method protocols from Synthetic Methods.
Reaction Type
Select a Reaction Type filter to display reactions that match that type.
For example, select Product Only to display the 116 product-only reactions.
Note: The Reaction Type filtering options that display are based on the result set. There may only be one option available if all results are of that type (e.g. Full).

Search Within Results
You may draw up to three structures to search for matches within the displayed reactions:
- Click the Draw button to open CAS Draw/ChemDoodle.
Note: Stereochemistry is ignored in the filter structure. - After drawing the structure, clicking the Cancel button returns you to the original result set; clicking the OK button generates a thumbnail image of the structure in the filter and provides the options to select As Drawn or Substructure search modes. Click the Search button to apply the filter.
- Click the Draw button to add another search within structure.
- The highlighting that appears in the results is based on the last structure added. Structures and be removed and edited by clicking the Remove and Edit link or can be permanently removed by clicking the X.
A summary of the structures applied is provided in the filtering dropdown; structures can be removed from the result set by deselecting the thumbnail image.
