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*).

Abstract

Existing studies used different scales to evaluate the quality of LED lighting by psychophysics experiments, which viewed specific objects. It is believed that for universal lighting, diverse objects are needed to evaluate color quality. In order to produce a suitable factors space to evaluate the quality of universal lighting, a psychophysics experiment was conducted, which used objects of different color or attribute. The experiments were carried out in darkrooms. In total, 44 observers viewed seven groups of objects to evaluate lighting quality. In this paper, factor analysis was used to reduce the large number of scales into fewer underlying independent factors. The results showed that objects of different color or attribute had an impact on visual perception, and three factors dominate visual perceptions: Attraction, Vividness and Warmth. Basing on this finding, a three-factor space was defined. The work was intended to set up a three-factor space as the help for the construction of LED lighting evaluation and application methods.
