Quick Question about cz.muni.fi.mias.search.Searching - Query String;

[fras2560]

For the method:

/**
     * Searches the index for query specified by string.
     *
     * @param query String with the query
     * @param print if true, results will be printed to standard output
     * @param offset index of the first retrieved result
     * @param limit number of results to retrieve
     * @param debug if true, results will contain debugging information
     *
     * @return Search result
     */
    public SearchResult search(String query, boolean print, int offset, int limit, boolean debug) {
        return search(query, print, offset, limit, debug, MathTokenizer.MathMLType.BOTH);
}

What does the query string look like?

I am sending it something like this:

<m:math>
          <m:semantics xml:id="m1.1a">
            <m:apply xml:id="m1.1.4" xref="m1.1.4.pmml">
              <m:plus xml:id="m1.1.2" xref="m1.1.2.pmml"/>
              <m:ci xml:id="m1.1.1" xref="m1.1.1.pmml">x</m:ci>
              <mws:qvar xmlns:mws="http://search.mathweb.org/ns" name="y"/>
            </m:apply>
            <m:annotation-xml encoding="MathML-Presentation" xml:id="m1.1b">
              <m:mrow xml:id="m1.1.4.pmml" xref="m1.1.4">
                <m:mi xml:id="m1.1.1.pmml" xref="m1.1.1">x</m:mi>
                <m:mo xml:id="m1.1.2.pmml" xref="m1.1.2">+</m:mo>
                <mws:qvar xmlns:mws="http://search.mathweb.org/ns" name="y"/>
              </m:mrow>
            </m:annotation-xml>
            <m:annotation encoding="application/x-tex" xml:id="m1.1c">x+\qvar@construct{y}</m:annotation>
          </m:semantics>
        </m:math>

Am I on the right track? It is giving me an error however:
