And also,

- same interface : users are not lost.
- Code already ported. Gui code tested. interraction with KIO-slave need to
be re-tested indeep...


and these problems:

Agree... there are already few B.K.O entries about this subject.


My thoughts currently go into these directions:

> engines' advanced search page


This already exist as well with Quick search. Of course code need to be
improved to include complex queries " à la google"...

But please, please, do not make a regular expression interface... You know
already my viewpoint about...

For standard users, this gives a well-known kind of interface, shows the

This is my recommendations :

- In a first time, port the current code to check if your new Search backend
work fine. This include Quick and Advanced search.
- In a second time, improve the quick search tools to include complex
queries.
- In 3th time, Look if new google like Search tool can be a good
remplacement of Advanced Search tool.

Marcel, you have forget an important point about searches : the dedicaced
user friendly tools :

- 1/ GPS location search using marble (this is the next one my my list).
- 2/ Duplicate images search using haar fingerprint.
- 3/ Fuzzy search images using haar fingerprint (like imgseek)

Others viewpoints are welcome of course form this room...

Best
