Hello to all,

some time ago I used beagle for indexing and searching,
now tracker is doing the job. Good work. However, there were some issues.

The tracker search tool finds files containing
12 Stones,
30 Seconds to Mars.

What it does not find are files containing words beginning with a
digit, as
2raumwohnung,
4lyn,
12stones.
That is the behavior of 0.8.17 and 0.9.15-0ubuntu0 on my system.


Thanks in advance,
Sebastian
