structure search with text search
Here a
search for all quinolines with antibacterial activity is performed.

Fig. 5: A search combining a structure search with a text field search.
Note
that the diagram is connected to the search term via the Boolean operator 'AND'.
Using Boolean operators helps you to find exact information faster and more easily
by focusing a search in the following ways:
AND retrieves only those records that contain both items, thus helping
to make a search more specific.
NOT also serves to narrow a search by retrieving records containing only
the first item, and excluding records containing the second term.
OR retrieves records
containing either or both of the items, and thus broadens a search.
Using
Boolean operators effectively will greatly improve your search results, by making
the results more specific.
