Files Lens is slow and incomplete

[Guillaume F]

Hi,
The Files lens is the slowest lens on my computer. I tried erasing my zeigeist folder (tip in bug #919801) and it worked to a certain extend, but it's still not quite right.
But my main problem is that the Dash cannot find files unless I write the whole name! When I look for a document and start typing a few letters, it does not appear. If I wait for the searching to stop (which takes quite some time, as previously stated), I get a lot of irrelevant files.
I thought the problem was with Zeigeist and indexing, but since I do find the document if I spell it out completely and since the same search works perfectly with Synapse, I guess the problem comes from the lens.
I'd be happy to give more information if I know what to give!

Am I the only one ? This bug is really quite upsetting because it completely udermines the advantages of searching in the dash.
