[Tracker] Full text search indexes only the first 64KiB of plaintext files?

[Aavo Tambur <aavo starman ee>]

Hi!

The full text search of Tracker does not seem to index anything beyond
the first 64KiB of plaintext files.
The command "tracker-info" of the file lists exactly the 64KiB as
nie:plainTextContent.

I thought I could use tracker to search within my source code files,
many of which are way bigger than 64KiB.
Why is that and is this something that can be changed?
