DEVELOPING COLDFUSION 9 APPLICATIONS

Accessing and Using Data

Left and right angle brackets are reserved for designating operators and modifiers. They are optional for the AND, OR,

and NOT, but required for all other operators.

Use double quotation marks in expressions to search for a word that is otherwise reserved as an operator or modifier,

such as AND, OR, and NOT.

To include a backslash in a search expression, insert two backslashes for each backslash character that you want

included in the search; for example, C:\\CFusion\\bin.

Operators and modifiers

You are probably familiar with searches containing AND, OR, and NOT. Verity has many additional operators and

modifiers, of various types, that offer you a high degree of specificity in setting search parameters.

An operator represents logic to be applied to a search element. This logic defines the qualifications that a document

must meet to be retrieved. You can use operators to refine your search or to influence the results in other ways.

For example, you can construct an HTML form for conducting searches. In the form, you can search for a single term.

You can refine the search by limiting the search scope in many ways. Operators are available for limiting a query to a

sentence or paragraph, and you can search words based on proximity.

Ordinarily, you use operators in explicit searches, as follows:

"<operator>search_string"

The following operator types are available:

Operator type

Identifies a concept in a document by combining the meanings of search elements.

Searches fields in a collection.

Specifies basic and intelligent word searches.

Specifies the relative location of words in a document.

Manipulates the score returned by a search element. You can set the score percentage display to four decimal
