Precedence Query Parser Implementation

Lucene Precedence Query Parser

The Precedence Query Parser extends the Standard Query Parser and enables the boolean precedence. So, the query <a AND b OR c AND d> is parsed to <(+a +b) (+c +d)> instead of <+a +b +c +d>.

Check StandardQueryParser for more details about the supported syntax and query parser functionalities.
