In my opinion there is a bug in BasicExpressionCompiler class in method
'isContentExpression'. It only checks if given element is equal to
Literals.CONTAINS. In result expression is created with
'propertiesExpressionFactory' instead of 'contentExpressionFactory' in
'createExpression' method within same class.
After fixing org/apache/slide/search/basic/BasicExpressionCompiler.java
< isContent = Literals.CONTAINS.equals(expressionElement.getName()) ||
< Literals.NOT_CONTAINS.equals(expressionElement.getName());
---
> isContent = Literals.CONTAINS.equals(expressionElement.getName());
query is working fine.
