Zeitgeist is using a huge amount of memory

[florin]

I use quite rarely Unity search, but I do use is both for software search and file search and after a while, zeitgeist gets to use huge amounts of memory. Right now, it uses 700+ MB of memory which is a lot. I really do not need that a program I use 15 times in 24 hours to eat almost as much as Firefox, a program I use all the time, sometimes with 100 tabs. See the screenshots.
