As Wendel said, Neo4j supports logical operators (`|, &, !, %`) in addition
to `colon (:)` operator (which is equivalent to `AND`). But colon and label
expressions can not be mixed in the same clause. For example:
`MATCH (n: A|B:C) RETURN n`
```
Neo.ClientError.Statement.SyntaxError
Mixing label expression symbols ('|', '&', '!', and '%') with colon (':') is
not allowed. Please only use one set of symbols. This expression could be
expressed as :A|(B&C). (line 1, column 13 (offset: 12))
"MATCH (n: A|B:C) RETURN n"
^
```
Another example of erroneous query is:
`MATCH (n: A:B), (m: (A&B)|C) RETURN n, m`
```
Neo.ClientError.Statement.SyntaxError
Mixing label expression symbols ('|', '&', '!', and '%') with colon (':') is
not allowed. Please only use one set of symbols. This expression could be
expressed as :A&B. (line 1, column 12 (offset: 11))
"MATCH (n: A:B), (m: (A&B)|C) RETURN n, m"
```
But using these different syntaxes in seperate queries is allowed
`MATCH (n: A:B:C) MATCH (m: (A&B)|C) RETURN n, m`
