If the schema-files note a type `string | AndOrTagConfigJson`, you can use one of these values.
In some cases, not every type of tags-filter can be used. For example, _rendering_ an option with a regex is
fine (`"if": "brand~[Bb]randname", "then":" The brand is Brandname"`); but this regex can not be used to write a value
into the database. The theme loader will however refuse to work with such inconsistencies and notify you of this while
you are building your theme.
Strict equality

Units' to rewrite to a default format.
Dates can be compared with the same expression: `somekey<2022-06-22` will match if `somekey` is a date and is smaller then 22nd june '22.

Regex equals

A tag can also be tested against a regex with `key~regex`. Note that this regex __must match__ the entire value. If the
value is allowed to appear anywhere as substring, use `key~.*regex.*`
Regexes will match the newline character with `.` too - the `s`-flag is enabled by default.
To enable case invariant matching, use `key~i~regex`
Regexes will match the newline character with `.` too - the `s`-flag is enabled by default. To enable case invariant

Equivalently, `key!~regex` can be used if you _don't_ want to match the regex in order to appear.

One can use `key!:=prefix-{other_key}-postfix` as well, to match if `key` is _not_ the same
as `prefix-{other_key}-postfix` (with `other_key` substituted by the value)
## Logical operators
One can combine multiple tags by using `and` or `or`, e.g.:
```json
{
"osmTags": {
"or": [
"amenity=school",
"amenity=kindergarten"
]
}
}
```
