Enter search terms
Pick the search-field "Word(s)" from the first drop-down box and enter the key word "gas turbine*" in the box to the right. - The quotation marks ensure that the multiple-word term is searched as a phrase. The wildcard character * guarantees the search for various forms of a word, eg various word-endings or singular and plural word forms. You may type either * or ? as wildcard characters - there is no difference between them.
In the second row of search terms, select "Word(s)" again and enter efficiency. Make sure that you have picked the Boolean Operator "AND" in the left selection-box to retrieve only those answers that contain both search terms.
Click the green "Search" button. - Please note: The price for the search fee is displayed below the Search button.
Helpful HINT: Since Boolean operators work within the search boxes, it is also possible to enter "gas turbine*" and efficiency in one single row!
