        Create and return the Query object represented by qstr. Null MAY be returned to signify there was no input (e.g. no query string) to parse.
        Throws:
        SyntaxError

                         throws SyntaxError
        Create a QParser to parse qstr, using the "lucene" (QParserPlugin.DEFAULT_QTYPE) query parser. The query parser may be overridden by local-params in the query string itself. For example if qstr={!prefix f=myfield}foo then the prefix query parser will be used.
        Throws:
        SyntaxError

      • getParser

        public static QParser getParser​(String qstr,
                                String parserName,
                                boolean allowLocalParams,
                                SolrQueryRequest req)
                         throws SyntaxError
        Expert: Create a QParser to parse qstr using the parserName parser, while allowing a toggle for whether local-params may be parsed. The query parser may be overridden by local parameters in the query string itself (assuming allowLocalParams. For example if parserName=dismax and qstr=foo, then the dismax query parser will be used to parse and construct the query object. However if qstr= {!prefix f=myfield}foo then the prefix query parser will be used.
        Parameters:
        allowLocalParams - Whether this query parser should parse local-params syntax. Note that the "lucene" query parser natively parses local-params regardless.
        Throws:
        SyntaxError
