After reading the links you pointed me to it seems that I can use REGEX to
query tracker. I am trying to use REGEX to match on the file names. I am
not at the moment interested in searching the content of the files.

So to find all my pdfs I used the REGEX search pattern:

tracker-search .*.pdf$

and i got 341 results, all of which were pdfs. so far so good. To find
all my .txt files (that is files ending with the txt file extension) i
used:

tracker-search .*.txt$

and got 138 results. This however did not return only the files ending
with txt but also some (but not all) files ending in .py. 

When trying to get *both* the .txt and .pdf files i tried two
different approaches. The first using the REGEX '|' and the second using
the tracker-search -r flag:

tracker-search '.*.(pdf|txt)$'
tracker-search -r .*.pdf$ .*.txt$ 

i got 14 and 445 respectively. I expected the same result from both.

So my questions are:
1. is this the correct mailing list to post these questions? 
2. can tracker-search understand REGEX directly or should i be using
tracker-sparql instead?

Thank you for your time,
