Public Methods

Method	Description
Get ( XCore.Mediator mediator, string propName, Func searchEngineFactory ) : SearchEngine	Gets the search engine.
Search ( IEnumerable fields ) : IEnumerable	Searches the specified fields. N.B. This version is currently only used in testing.
SearchAsync ( IEnumerable fields ) : void	Searches the specified fields asynchronously.

Protected Methods

Method	Description
DisposeManagedResources ( ) : void	Override to dispose managed resources.
FilterResults ( IEnumerable results ) : IEnumerable	If some objects need to be filtered out of the results (for instance the item we started from in the merge dialog) then this function can be used to do it.
GetSearchableObjects ( ) : IList	Gets the searchable objects.
GetStrings ( SearchField field, ICmObject obj ) : IEnumerable	Gets the searchable strings of an object.
IsFieldMultiString ( SearchField field ) : bool	Determines if the specified field is a multi-string or multi-unicode field.
IsIndexResetRequired ( int hvo, int flid ) : bool	Determines if an index reset is required.
SearchEngine ( SIL.FieldWorks.FDO.FdoCache cache, SearchType type ) : System	Initializes a new instance of the SearchEngine class.
