How to create a personal search engine

Question

I have a ton of data on the web built just for me:

• gmail
• Delicious Bookmarks
• Flickr
• Facebook

Also, some local data that should be sent to a central index:

• browser history

As well as some local data that I do not want to leave the machine:

• My Documents

Is there a simple way to build a search engine for all of this data? Of course, security would be a primary concern. I would probably want something that would have the following process:

1. Check local files' index (eg My Documents)
2. Check my centralized index (eg gmail)
3. Check Google

Answer 1

You may try Google Desktop Search (Linux, Windows), Beagle (Linux), Tracker (Linux) desktop indexing softwares.
