[Tracker] search match on substrings

["Brian J. Murrell" <brian interlinx bc ca>]

So, I have a PDF indexed which has the following nie:plainTextContent
from the extractor in it:

$ /usr/libexec/tracker-extract -f tmp/Fence\ Bylaw.pdf
...
 nie:plainTextContent "...\nBY-LAW NO. 2003-405\n..."

Should any subtring return a match hit?  i.e.:

$ tracker-search -l 1000 BY-LAW --disable-color
Results:

Although even matching the exact string doesn't hit:

$ tracker-search -l 1000 "BY-LAW NO. 2003-405" --disable-color
Results:

I am able to match at least one hit in that file, so it must be indexed:

$ tracker-search -l 1000 Exemptions --disable-color
Results:
...
  file:///home/brian/tmp/Fence%20Bylaw.pdf
  ...Pool Fences Exemptions Offence and Penalty...


Ideas?

Cheers,
b.

P.S. Sorry to be such a pain on all of this, but I'm trying to evaluate
tracker for suitibuility here and being accurate and complete is a
requirement.
