Searching the Topic Field
Enter Topic terms to search the following fields within a record.
Enter your search terms in any order. The product returns every record containing all your search terms. To look for an exact phrase, use quotation marks. Example: "global warming"
Right- and Left-hand Truncation
Both right- and left-hand truncation are allowed when using wildcards (* $ ?) in Topic and Title searches. You must enter at least three characters after a wildcard when used at the beginning of a word and three characters before a wildcard when used at the end of a word.
The following are valid search examples when using right-hand and left-hand truncation.
The following are invalid search example since they do not include three characters before or after the wildcard.
Implied AND Operator
Remember that the product uses an implicit AND operator when you enter two or more adjacent terms in most fields thereby allowing you to save time and effort when creating and entering search queries. For example:
Entering rainbow trout fish farm in a Topic or Title search is equivalent to entering rainbow AND trout AND fish AND farm -- both queries return the same number of results.
Using Formulas when Searching
Separate alphanumeric characters when entering a formula in your search query. Alphanumeric characters are indexed in the database as terms and each character is separately indexed.
For example, in a Topic or Title search, the query K x Fe 2-y Se 2 returns multiple results including the following article: "The electron pairing of K(x)Fe(2-y)Se(2)"
Notice that some of the characters in the title of the article are surrounded by parentheses. They are considered separators--they are not needed in a search query although you may use them.
To get an exact match, always use quotation marks in your search. For example, "K x Fe 2-y Se 2" returns multiple result.
Caution: Always use a space between the alphanumeric characters in the search query. A query such as "KxFe2-ySe2" (with or without quotation marks) will not return any results.
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.
Spelling of Search Terms
The product automatically finds spelling variations (such as U.S. and U.K. spelling differences) in Topic and Title search terms. If you enter a U.S. term, the product automatically searches for the equivalent spelling and vice-versa.
For example, if you enter color in the Title field, the product finds all records that contain the term color and/or colour in the article title.
To turn off the this feature, enter a term using quotation marks ( "" ). For example:
