Examples: add tags support to search

[makc]

e.g. rename webgl_postprocessing_unreal_bloom_selective.html to webgl_postprocessing_glow_unreal_bloom_selective.html, and the other one too.

because people typing "glow" in examples search box get nothing.

This suggestion does make sense. It's just a bit unfortunate how long the file names are now.

Do we really need the bit unreal in these names? Exchanging unreal with glow seems a nice tradeoff.

[mrdoob]

I don't think we need unreal, but I don't know how to solve glow vs bloom.

[makc]

well unless you are going to implement some tags syste, it has to be file names, right?

[mrdoob]

We could implement some internal query replacement code.

Pseudo code:

if ( search === 'glow' ) search = 'bloom';

[makc]

@mrdoob then there will be no results until full word is typed. what if someone types glo and, seeing there is nothing, stops typing?

[mrdoob]

With the current code that is correct. We could make the code a bit smarter too.

Just trying not to end with webgl_postprocessing_glow_bloom_shine_foo_bar_selective.html.

[makc]

so the tag system then? such that every example would have a number of tags attached to them, and these tags would be searchable as well

[mrdoob]

So in https://github.com/mrdoob/three.js/blob/dev/examples/files.js we could add:

var tags = {
    "webgl_postprocessing_unreal_bloom_selective": [ "glow" ]
};

@makc I make draft PR #18773, can you finish it using this reference?
It is ok that I am added tags into a file definition?

[makc]

@munrocket Im not sure how do I finish somebody elses PR. or do you mean forking your fork and then submitting PR into your fork?

[munrocket]

You can copypaste it and make it as your on PR and I will close draft.

[munrocket]

I don’t want to wipe all the history in this file by myself. So help me please.
