Remove undesired articles from search

Fix #137

[bparks13]

@cjsha Just to confirm, this PR is only removing the pages from the search, whereas the original issue is trying to keep the pages from being generated at all. If this PR marks that issue as resolved, then we would still have the pages being generated and rendered if someone types the name into the link (why they would ever do that I don't know). If we want to keep #137 as an open issue we can unlink it from this PR and merge this, since it is a good fix to remove them from search to reduce visibility.

Edit:

Ignore everything I said, I see that you created a new issue doing exactly what I said!

I'm going to approve this as it does what is purporting to do, which is hide the pages with no properties from the search (specifically, this works for DeviceNameConverter).

However, during testing I noticed some strange behavior with the search algorithm, which may or may not be controllable by us directly.

If I type "context t", I can see the ContextTask pop up:

However, if I type "contextt" (no space), no results appear:

We explicitly add the ContextTask to the TOC, under DataElements, so therefore it should appear in the search. This behavior may exist for other pages, but I did not test more than this.

I made another issue #261 to prevent unnecessary pages from being generated. This one is just going to remove them from search.

the docfx search is super finnicky e.g. dotnet/docfx#10560. I think what you're seeing is that they insert a zero-width space in some places.

We should actually consider upgrading to docfx 2.78.3 which includes this PR
