PT Polocies and FAQ

[Eugen]

I'm not sure what you mean by this. There is search by filename, filename and description, entire header, or entire file.

I not see on PT a search input field where I could input "Ruler" word (or any other word from Description) or "helper2druler100ldu.dat" (file name) as search query to find the next part: https://library.ldraw.org/tracker/37573

This part could be found only with "Category:Helper" filter (also with "Author" filter, but without "Category:Helper" filter actually there would be a long list of all parts).
