Description

If, in an expression, a value with a whitespace char is directly preceded by a special char "[" or "(", whitespace char in the value gets replaced with space.

This does not happen, if there is a space between "[" and a double quote in the expression.

For example, if we have a document with cat_s field containing a value "57\n157", following query works:

"q":"cat_s:[ \"57\n157\" TO \"57\n157\"]",
"defType":"edismax"

but

"q":"cat_s:[\"57\n157\" TO \"57\n157\"]",
"defType":"edismax

does not, as lower boundary value gets replaces with "57 157" in ExtendedDismaxQParser after following calls

List<Clause> clauses = splitIntoClauses(userQuery, false);
String mainUserQuery = rebuildUserQuery(clauses, config.lowercaseOperators);

As a workaround, we need to add a space before a double quote in expressions.
