structure, substructure, and/or similarity) is<br />

determined by what you have selected in the Search<br />

menu.<br />

To find the current molecule:<br />

1. Browse to the record containing the structure<br />

of interest.<br />

2. From the Search menu, choose the type of<br />

structure search you want to perform.<br />

3. From the Search menu, choose Find Current<br />

Mol.<br />

ChemFinder begins the search and displays the<br />

search status on the lower right corner of the status<br />

bar. When the search is complete, the form displays<br />

the first hit, and the list you can browse is restricted<br />

to the records hit by the query.<br />

Entering a Reaction Query<br />

The general procedure for creating a reaction query<br />

is very similar to creating a structural query.<br />

Clear the form:<br />

• From the Search menu, choose Enter Query.<br />

The form clears.<br />

2. From the Search menu, choose Find.<br />

The search proceeds as with simple structure<br />

searching.<br />

Special Structure<br />

Searches<br />

The Find Structures submenu on the Search menu<br />

provides for several common types of searches that<br />

would be awkward or arcane to conduct using<br />

regular means. As with other searches, all of these<br />

searches operate within the current record set if the<br />

Over Current List option is in effect. Otherwise, the<br />

whole list is searched, regardless of how many<br />

records are currently displayed.<br />

ChemFinder<br />

Enter the query:<br />

1. Double-click in the Structure box.<br />

The ChemDraw ActiveX toolbar appears.<br />

2. Draw the structure or substructure or reaction<br />

in the From ChemFinder window.<br />

3. Click somewhere in the form outside the<br />

Structure box.<br />

Now you can enter more query terms in the other<br />

data boxes for a combined search.<br />

1. From the Search menu, select or deselect the<br />

Substructure option.<br />

NOTE: The Similarity option is not available for<br />

reaction queries.<br />

These are generic searches, made without entering<br />

any query information. The options are:<br />

• Empty Structures—Locates records<br />

containing no structure. It is equivalent to<br />

specifying a molecular weight of zero in a<br />

regular search. It is provided because the latter<br />

method is a bit obscure.<br />

• Reactions—Locates structures that are<br />

reactions. The same effect can be achieved by<br />

entering a bare arrow as a structure query.<br />
