org.rssowl.core.model.search.ISearchCondition
Instances of ISearchCondition are grouped under a single Search. Each condition is connected with the others of the search through the value of isAndSearch() in the SearchMark that contains N conditions, such as:
- If TRUE, News have to match all Condition
- If FALSE, News that dont match this Condition have to match at least one other Condition
The condition contains the affected ISearchField, which maps to a specific Field in the persistance layer.

The specififer maps to an Enumeration of possible values. They describe how the Search-Value should be used while searching. Some values are "is", "is not" and "begins with".

Last but not least, a call to getValue() returns the value of this condition.

Example of a SearchCondition: "Title is'nt 'RSSOwl'"
where:
- Title belongs to ISearchField
- is'nt belongs to ISearchSpecifier
- 'RSSOwl' is returned by getValue()
A group of search-conditions may or may not be related to a ISearchMark. If they are related, that basically means that the search is stored in the persistance-layer and is displayed in the List of Marks.
