1. Should we be adding sharemem to the dll template?

2. If I call a textfilter should I dedup the word list in there or is it more efficient/effective to leave it? I can't see anyway of doing it in a wordgenerator so I'm assuming that you do it at some later point.

Only if you wish to do so.  The DLLs are such that they don't pass any long
strings, etc. that need it, so it is strictly up to you.

Just leave them in there, EDB will take care of the dups based upon the
proper collation rules, etc.

duh - TextToFilter, FilteredText?

I know EDB will take care of them, I don't know how, so I wondered if it would be more faster if I did it in the textfilter where I'm having to handle all the characters (and by implication words) anyway?

These are the actual DLL function signatures:

  function ValidateEDBModule(ModuleType: Integer): Boolean; stdcall;
  function OpenEDBModule(var ModuleHandle: Integer): Boolean; stdcall;
  function CallEDBWordGenerator(ModuleHandle: Integer;
                                Collation: Integer;
                                TextData: pEDBChar;
                                TextLength: Integer;
                                WordData: pEDBChar;
                                WordLength: Integer;
                                var ResultWordLength: Integer;
                                var Position: Integer;
                                SearchWords: Boolean): Boolean; stdcall;
  function GetEDBModuleErrorMsg(ModuleHandle: Integer;
                                ErrorMsg: pEDBChar;
                                var ErrorMsgLength: Integer): Boolean;
stdcall;
  function CloseEDBModule(ModuleHandle: Integer): Boolean; stdcall;

EDB does a lot of prettying up of the calls for you into a nice custom
module for Delphi that you use with the event handlers, etc.

EDB uses a sorted word list with a binary search for finding/inserting the
words to be indexed, so it's pretty fast.
