d. Click Add Subjects to have the subject(s) appear on your list in the Advanced Search
Step 3. Add keywords to your search
Because you are looking for results pertaining to the subject of hunting “whales”, you’ll need to add additional keywords to your search to refine it to that specific aspect of marine hunting.
Tip: To return the most results, truncate your keywords at the word stem. For example: whale* whaling* orca*. Using an asterisk “*” retrieves various endings (e.g. whale* for whale, whales). Be sure to separate the keywords with a space.
Step 4. Add an additional search clause
Click the + in lower right hand side to add more subject and keyword terms.
Step 5. Modify the instructions in Steps 1 and 2 to Find OCM subject(s) for “weapons”
Begin by clicking on “Add Subjects” to open the subject selection menu, then use the tabs to find matching subjects for your topic in one of the following ways:
a. In the A-Z Index tab, enter the word “weapons” into the Filter Index box.
b. In the Major Subjects tab, select “Technology and Material Culture”, then “Tools and Appliances”, and then Weapons (OCM 411).
c. In the OCM Code tab, navigate to OCM 411 in the range to find “Tools and Appliances”.
Step 6. Add additional keywords (optional)
In addition the OCM subject “weapon”, you can also use keywords to refine your search. Truncate words at the word stem and put spaces between the words to return more inclusive results: spear* harpoon*
Step 7. Set your Boolean operators!
