"Water consumption" finds records containing the exact phrase
Water AND consumption finds records containing the words water and
consumption. The two words may appear in the same Topic field or they may be in
different Topic fields.
Water consumption (without quotation marks) is equivalent to the search
water AND consumption.
Water AND consum* finds records containing the words water, consume,
consumed, consumer, consumption, and so on.
Water SAME consumption finds records containing the words water and
consumption in the same sentence.
Water OR consumption finds records containing either water or consumption
or both words.
Use quotation marks to find exact phrases. For example, "soil drainage"
finds soil drainage, but not drainage of soil.
Use terms without quotation marks to find records that contain those terms.
For example, soil drainage finds soil drainage, drainage of soil, soil
type and drainage, and so on.
Use the SAME operator to find words in any order in the same sentence. For
example, soil SAME drain* finds soil drainage, drainage of soil, well-drained
soil, and so on.
Certain frequently used words such as articles (a, an,
the), prepositions (of, in, for, through), and pronouns (it, their, his) are not
searchable in the Topic field. These stopwords may
be entered as part of a phrase, but they are not searched. For example, the phrase
"men versus women" returns records that include the words men
and women, but versus is ignored because it is a stopword.
