Thanks Erick for the response. I tried to debug the query. Below is the response in the debug node
<str name="rawquerystring">Rahul - kumar</str><str name="querystring">Rahul - kumar</str><str name="parsedquery">+text:Rahul -text:kumar</str><str name="parsedquery_toString">+text:Rahul -text:kumar</str><lst name="explain"/><str name="QParser">LuceneQParser</str><arr name="filter_queries"><str>Rahul - kumar</str></arr><arr name="parsed_filter_queries"><str>+text:rahul -text:kumar</str></arr> Does it mean the query parser has parsed it to tokens "Rahul -" and "kumar"? Even if this was the case solr should be able to retrieve the documents because I have indexed all the documents based on n-grams as well.
