    Only index text/plain MIME types, never index source code
    
    Tracker isn't and never will be a sourcecode indexer. Source
    code is often huge, and it requires some understanding and
    tokenization of the contents in order to effectively create
    an index. Tracker indexes text documents by copying the
    first 1MB of data from each file into an SQLite database.
