Tracker failes to index .qmd (text) files

Applications
1

I work a lot in R with Quarto Markdown Files (.qmd). They are simple text files, with an extended markdown language.

I know for instance, of a .qmd file in a sub/sub/sub directory of my home folder which contains the word ‘opioids’.

When I search (using Files/Nautilus) for ‘opioids’ (Full Text - not File Name), I get lots of results based on content, including pdf files, libreoffice files, markdown (.md) and HTML, but not .qmd files at all.

If I limit the search (What) to just Text Files, I still get results based on content, but markdown (.md) files are not displayed … and neither are any .qmd files.

If I limit the search (What) to Other Type and specify Quarto Markdown File - nothing at all is listed.

I have changed the setting for text-allowlist to include ‘*.qmd’ – makes no difference.

I have made sure, to remove .git from the ignored-directories-with-content as I often use git for version control of manuscripts.

After these changes, I have tried to reset and re-index - nothing helps.

I am at a loss, now and any help is appreciated.

Hi,

What mime type is reported if you run: xdg-mime query filetype for one of the .qmd files in question?

You already spotted the text allowlist, which is specific to the plaintext extractor. All extractors also have a .rules file, e.g. /usr/share/tracker3-miners/extract-rules/15-text.rule

[ExtractorRule]
ModulePath=libextract-text.so
MimeTypes=text/plain;text/markdown
FallbackRdfTypes=nfo:Document;nfo:PlainTextDocument;
Graph=tracker:Documents
Hash=099925eabaa7a05a96418129b1f22e8510862c9287c4bb47522b4f150af5f62d

Notice how there’s a specific list of mime types that will be processed. I’m just guessing here but maybe qmd files have a different mimetype reported?

Hi,
xdg-mime reports: text/x-quarto-markdown

I added text/x-quarto-markdown to the 15-text.rules file, like so:
MimeTypes=text/plain;text/markdown;text/x-quarto-markdown

Still no .qmd files in the search result, but I suspect the miners need to re-trawl $HOME for .qmd files…

sadly, still no .qmd files in search results

Hi,

You may also need to change the Hash field in the .rule file so tracker-miners only requires a restart to reindex the affected files, instead of a database reset.

And you might prefer to use a standalone .rule file for .qmd files alone, as that will not be overwritten by future system updates. This file would need MimeTypes/Hash fields changed, compared to the stock 15-text.rule, and I would suggest to prefix this file with 99- to avoid conflicts with possible upstream changes.

Cheers,
Carlos

I have created a new 99-text-qmd.rule file as you suggest

Sorry to be a bit of a noob here, but the hash listed in the file, should that be an md5sum or sha1sum or some other hashing algorithm … and that hash has to be calculated on the file without the ‘hash’ line?
