This sounds very interesting. Wanted something similar, so going to check it out:)

One thing at first look, like a little feature request ;).

Personally I think it would be very nice if it was possible to index different sites to different search indexs. So you could separate different stuff, like job, different projects you have, and other stuff and then last everything else etc to there on search index db.

So it would be possible to have like "profiles" you could easy choose from. So in the addon, when you click on the hister icon on the toolbar there would be a list of profiles that you could choose where to index the site to. But also a setting to choose which domains and sites that always should index to one search index profils. And all sites that dont is added to a profile is added to the default index instead.

For me this would make it much more easy to find stuff and sort out what Im looking for (for me things get very "thing"/project based what I want to find), so having this..

1 - The "profiles" would become like an important filter. When you search you could easy mark one or more "profiles" which you would search from, and you remove alot of unwanted data automatically, specially when you index every site you visit by automatically.

2 - It would also make it easy if the db gets big over time to remove data that is less important later on and that you dont need to be index anymore.

3 - It would also make it easier to backup only the most important search index DB:s if the DB for the differnt search index:s where in different folders/files. I guess the "default index" that index all sites could easy get big, but there it would be alot of not important data. So would be nice to be able to easy just use a backup program and only backup the only important search databases, to save space.

Thanks
