other nested groups) connected through a unique logic operator (AND is assumed for 'space')

| |
ChildElements |
Returns a list of Element objects, representing the sub elements of the query.
| |
Configuration |
The instance of the Configuration class that holds the settings to be used.
(Inherited from Element.) | |
Content |
Returns a string representing the content of the element, this should typically be;
WordElement.Content => theWord
NotWordElement.Content => -theWord
GroupElement.Content => null
PhraseElement.Content => thePhrase (no quotes)
(Overrides Element.Content.) | |
CreateLexiconQueries(SearcherIO) |
Creates the LexiconQuery for this element.
(Overrides Element.CreateLexiconQueries(SearcherIO).) | |
CreateWordSubgroup(String) |
Creates an Element based on the parameter.
| |
elementQueryCollection |
The lexicon queries used for the element
(Inherited from Element.) | |
elements |
The Element objects within the group.
| |
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) | |
Finalize()()()() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
GetChildElementContents()()()() |
Returns ArrayList of all child element .Content properties
| |
GetHashCode()()()() | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetIgnoredWords()()()() |
Returns the stop words from the original query that were ignored.
(Overrides Element.GetIgnoredWords()()()().) | |
GetMatchingDocumentIDs(SearcherIO, IntHashtable, SearchOptions, Hashtable) |
Gets all document IDs matching this group.
(Overrides Element.GetMatchingDocumentIDs(SearcherIO, IntHashtable, SearchOptions, Hashtable).) | |
GetType()()()() | Gets the type of the current instance. (Inherited from Object.) | |
GroupOperator | The logic operator that all elements in the group are bound with (AND or OR).
| |
IsStopWord()()()() |
Whether is stop word.
(Inherited from Element.) | |
MemberwiseClone()()()() | Creates a shallow copy of the current Object. (Inherited from Object.) | |
ParseExpression(String) |
Loads the elements field with elements (words, phrases, groups, logic operators) in expression.
| |
RemoveOperatorAmbiguities()()()() |
Removes operators ambiguities
(if there are both "AND" and "OR" operators in a group, re-adjust groups like: (x OR y) AND z)
| |
RunLexiconQueries(SearcherIO) |
