Annoying. It appears that Google Search no longer allows the chaining of site: and inurl: in the same search query.
For instance…
site:www.moma.org/documents/ inurl:catalogue -“press release”
site:www.moma.org inurl:catalog
… and similar variants.
DuckDuckGo search has no such problem, though for full-text .PDFs you do need to knock out the MoMA giftshop at store.moma.org …
site:moma.org/documents/ inurl:catalogue -store
And the Duck censors certain results. Presumably certain MoMA catalogues are from artists whose names trigger the censorship filters?
