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.
