Combine previous searches in Search history

As your research evolves, you might want to combine some of your previous queries to run a new search.

Combine previous queries using check boxes of searches

  1. From the Combine searches box in Search history, select the check boxes of the searches you want to combine. The numbers of the searches will appear in the Combine searches box.
  2. Click the magnifying glass icon to run the search.

Combine previous queries by entering numbers of searches

  1. Enter the numbers of the searches you wish to combine directly into the Combine searches box. Each query number must be preceded by a # sign to combine searches (e.g., #1 AND #2, combustion AND #2, #5 AND #4, NOT #3).

    Refer to the next section for detailed information about running Boolean operator searches for the combined queries.

  2. Click the magnifying glass icon to run the search.
Example #1 and #2

Important If you enter a number without the # sign, Engineering Village searches for just that number, not the number of your search shown in Search history. Therefore, if you enter #1 petroleum and 2, Engineering Village searches for petroleum-related articles and the number 2.

Use Boolean operators in Combined Search

You can combine the searches using Boolean AND, OR, and NOT operators.

  1. From the Combine searches column in Search history, select the down arrow for your first search and click Start. The filled check box will display to confirm your first selection.
  2. Click the down arrow for your second search and select the Boolean operator (And, Or, Not) from the drop-down. The filled check box will display to confirm your second selection.
  3. Continue this process for all searches in your Search history that you want to combine. The output numbers of these selections display in the Combine searches box.
    NoteYou may also enter the numbers of the searches directly into the Combined searches box.
  4. Use nesting parentheses to specify the order of the processing in the Combined searches box.
    Example(#1 or #2) and #3
  5. You can also add additional search terms with item numbers:
    Example#1 and diodes wn KY

    (#1 and #2 ) and Elsevier wn PU

Note Only searches that are run in the same database (or same combination of databases) are able to be combined.
