Certain documented methods are missing from search results

[AhmedAlaa4611]

I noticed that some documented methods do not appear in the search results even though they exist in the documentation pages. For example:

• assertClientError() method appears in the HTTP tests docs but is not searchable.
• Some other methods appear in the Hidden Context docs but also are not searchable:

Context::addHidden(/* ... */);
Context::addHiddenIf(/* ... */);
Context::pushHidden(/* ... */);
Context::getHidden(/* ... */);
Context::pullHidden(/* ... */);
Context::popHidden(/* ... */);
Context::onlyHidden(/* ... */);
Context::exceptHidden(/* ... */);
Context::allHidden(/* ... */);
Context::hasHidden(/* ... */);
Context::missingHidden(/* ... */);
Context::forgetHidden(/* ... */);

This makes them difficult to discover unless users already know where to look. It would be helpful if we ensure that all documented methods are indexed and searchable.

There may also be other documented methods affected that I haven’t noticed yet, which makes this a broader discoverability issue for developers relying on search.

Thanks for your work on the docs!
