Let search for CO2 show CO₂ too - WITH enabled "Match Diacritics"?

[pstein]

If I search in Everything for "CO2" it list only files which contain the exact "CO2" pattern but not the files with "CO₂"

Therefore I have to disable "Match Diacritics".

Then CO2 matches "CO2" AND "CO₂" filename pattern.

But on the other hand disabling "Match Diacritics" will not distinguish between "a" and german Umlaut "ä".
This is bad too.

So what I need is a search with
1.) "Match Diacritics" enabled
AND
2.) "CO2" matches "CO₂"

What solution can you offer?

I don't need a general purpose solution for ALL superscript and subscript number and char combinations.

It would be sufficient to have an user editable short list feature which let users define customized equivalents similar to
CO2 = CO₂

...which could later be extended to other synonym combinations like

USD = Dollar
Mike = Michael
Department = Dept
.....

Sorry, I don't have a good solution here for Everything 1.4 / 1.5.

A synonym list is on my TODO list.

Everything 1.5.0.1407a adds basic support for Synonym Lists.

I'll assume that the only desire here was a simple list of synonyms

this;that;other

so nothing like

this;that;ww:other

Correct.

You cannot substitute search modifiers or search functions.
substitution only occurs for normal searches (eg: doesn't apply to regex)
