Provides a set of flags to be used with IQueryParser::SetOption and IQueryParser::GetOption to indicate individual options.

public enum StructuredQuerySingleOption

Fields

AutomaticWildcard = 4

The value should be VT_BOOL with VARIANT_TRUE to generate query expressions as if each word in the query had a star appended to it (unless followed by punctuation other than a parenthesis), or VT_EMPTY or VT_BOOL with VARIANT_FALSE to use the words as they are (the default). A word-wheeling application will generally want to set this option to true. Retrieving the option always returns a VT_BOOL.

ConnectorCase = 10

This setting decides whether there are special requirements on the case of connector keywords (such as AND or OR). The value must be a VT_UI4 that is a CASE_REQUIREMENT value. It defaults to CASE_REQUIREMENT_UPPER_IF_AQS.

ImplicitConnector = 9

This setting decides what connector should be assumed between conditions when none is specified. The value must be a VT_UI4 that is a CONDITION_TYPE. Only CT_AND_CONDITION and CT_OR_CONDITION are valid. It defaults to CT_AND_CONDITION.

LanguageKeywords = 6

The value must be a VT_UI4 that is a LANGID. It defaults to the default user UI language.

Locale = 1

The value must be VT_EMPTY (the default) or a VT_UI4 that is an LCID. It is used as the locale of contents (not keywords) in the query to be searched for, when no other information is available. The default value is the current keyboard locale. Retrieving the value always returns a VT_UI4.

NaturalSyntax = 3

The value should be VT_EMPTY or VT_BOOL with VARIANT_TRUE to allow natural query syntax (the default) or VT_BOOL with VARIANT_FALSE to allow only advanced query syntax. Retrieving the option always returns a VT_BOOL. This option is now deprecated, use SQSO_SYNTAX.

Schema = 0

The value should be VT_LPWSTR and the path to a file containing a schema binary.

Syntax = 7

The value must be a VT_UI4 that is a STRUCTURED_QUERY_SYNTAX value. It defaults to SQS_NATURAL_QUERY_SYNTAX.

TimeZone = 8

The value must be a VT_BLOB that is a copy of a TIME_ZONE_INFORMATION structure. It defaults to the current time zone.

TraceLevel = 5

Reserved. The value should be VT_EMPTY (the default) or VT_I4. Retrieving the option always returns a VT_I4.

WordBreaker = 2

This option is used to override the default word breaker used when identifying keywords in queries. The default word breaker is chosen according to the language of the keywords (cf. SQSO_LANGUAGE_KEYWORDS below). When setting this option, the value should be VT_EMPTY for using the default word breaker, or a VT_UNKNOWN with an object supporting the IWordBreaker interface. Retrieving the option always returns a VT_UNKNOWN with an object supporting the IWordBreaker interface.
