detail: string substr(string text, int start, int length)
doc: |
Cuts a substring from a string starting at "start" up to "length" characters. The first character position is 0 (zero).
- If start is negative - it indicates starting position from the end of the string (for example `substr("test", -2, 2)` will return last 2 charactes: "st").
- If start is negative - it indicates a position starting from the end of the string (for example `substr("test", -2, 2)` will return last 2 charactes: "st").
- If length is negative - it means so many characters will be omitted from the end of string (example: `substr("test", 0, -2)` will return string without last 2 characters: "te").
- If length is zero - it will return a string from the starting position to the end of the string. **New behavior** for sfall 4.2.2/3.8.22

doc: |
Returns position of a first occurance of a needle string in a haystack string (starting from a given 0-based position), or -1 if not found.
- If pos is negative - it indicates starting position from the end of the string, similar to substr().
Works the same as `string_pos`, except you can specify the position to start the search.
- If `pos` is negative - it indicates a position starting from the end of the string, similar to `substr()`.
