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

Horiba's innovative gas analyzer, the Mexa-One XL-NX, leverages Infrared Laser Absorption Modulation (IRLAM) technology to measure nitrogen compounds in exhaust gas with high precision and speed. This technology is crucial for the development of exhaust gas aftertreatment systems and engines running on alternative fuels. The article explores the challenges posed by upcoming emissions standards and the growing use of alternative fuels. It also compares IRLAM to conventional methods like NDIR and FTIR spectroscopy, highlighting IRLAM's superior detection limits, accuracy, and computational efficiency. The Mexa-One XL-NX is designed to operate in various conditions, including those with high water content in exhaust gas, and can be integrated into portable emission measurement systems. The article concludes by discussing potential future developments, such as measuring additional gas components and on-board measurements.
