Hi Pulkit, In case you are using the standard contrib query parser (equivalent to lucence QP), you may want to create a QueryNodeProcessor, that will convert TermQueryNodes to WildcardQueryNodes, and attach it to the processor pipeline:
StandardQueryParser qp = new StandardQueryParser(); ((QueryNodeProcessorPipeline) qp.getQueryNodeProcessor()).add(new MyQueryNodeProcessor()); // qp is ready for use Please, let me know if you have any question about how to implement your own QueryNodeProcessor.
