I have read a lot of complaints about indexing and understand them all. However, I can see the merits of indexing and think it should be a must for L4. We need to remember that this is a product for the future and hard disk space, while it may be a dilemma now is certainly not an issue on recently built machines. Unfortunately, Logos is "caught between a rock and a hard place".
I don't know what it involves, but can I suggest that their is an OPTION to ignore/turn off indexing so that searching could be carried out as per L3. In this way, those who have slow machines could search immediately and perhaps save some HD space, but for those who have both may be happy to persevere with the indexer. Having the option seems to me to be the way forward.
