Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Excerpt

Liebherr's development of a hydrogen combustion engine with a Port Fuel Injection (PFI) system marks a significant step towards decarbonizing heavy-duty applications. The engine's robustness, reliability, and responsiveness make it suitable for demanding construction machinery, offering near-zero greenhouse gas emissions and excellent efficiency. The article discusses the successful testing of the PFI system, which has shown promising results in terms of performance and dynamic behavior. Liebherr aims to achieve a level of performance equivalent to diesel engines, paving the way for low-emission powertrains in machine fleets. A pilot project with Strabag at the Austrian Kanzelstein quarry will demonstrate the potential of hydrogen engines in reducing emissions in the construction sector. The use of climate-neutral hydrogen produced with renewable energy sources is highlighted as a key enabler for achieving climate neutrality goals.
