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

|
| AddMissingOperatorsAsAnd()()()() | Obsolete.
Obsolete - Renamed to AddMissingOperators, please use new name.
|
 | 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) | (Inherited from Object.) |
| Finalize()()()() | (Inherited from Object.) |
| GetChildElementContents()()()() |

(if there are both "AND" and "OR" operators in a group, re-adjust groups like: (x OR y) AND z)
|
