I installed it yesterday and noticed that it doesn't actually index much. It should be, but it's not, the pages aren't added. If they are in the index, it finds them in a search, but very few pages are.

Oli here from Memex.

It may be that you have not touched the indexing preferences (which only index pages that are visited for more than 5 seconds)

Is that the reason, or does it still not work?

No, I changed everything (set it to 20 seconds), it still doesn't work. I stay on pages (here, for example) for minutes, and they don't get indexed. I have disabled the bar and hotkeys, if it matters.
