/**
 * Returns a search pattern based on a given Java element.
 * The pattern is used to trigger the appropriate search, and can be parameterized as follows:
 *
 * @param element the Java element the search pattern is based on
 * @param limitTo determines the nature of the expected matches
 *   <ul>/*w ww .  j  av  a 2 s. co m*/
 *    <li>{@link IJavaSearchConstants#DECLARATIONS DECLARATIONS}: will search declarations matching
 *          with the corresponding element. In case the element is a method, declarations of matching
 *          methods in sub-types will also be found, allowing to find declarations of abstract methods, etc.
 *            Some additional flags may be specified while searching declaration:
 *            <ul>
 *               <li>{@link IJavaSearchConstants#IGNORE_DECLARING_TYPE IGNORE_DECLARING_TYPE}: declaring type will be ignored
 *                     during the search.<br>
 *                     For example using following test case:
 *               <pre>
 *                  class A { A method() { return null; } }
 *                  class B extends A { B method() { return null; } }
 *                  class C { A method() { return null; } }
 *               </pre>
 *                     search for <code>method</code> declaration with this flag
 *                     will return 2 matches: in A and in C
 *               </li>
 *               <li>{@link IJavaSearchConstants#IGNORE_RETURN_TYPE IGNORE_RETURN_TYPE}: return type will be ignored
 *                     during the search.<br>
 *                     Using same example, search for <code>method</code> declaration with this flag
 *                     will return 2 matches: in A and in B.
 *               </li>
 *            </ul>
 *            Note that these two flags may be combined and both declaring and return types can be ignored
 *            during the search. Then, using same example, search for <code>method</code> declaration
 *            with these 2 flags will return 3 matches: in A, in B  and in C
 *    </li>
 *       <li>{@link IJavaSearchConstants#REFERENCES REFERENCES}: will search references to the given element.</li>
 *       <li>{@link IJavaSearchConstants#ALL_OCCURRENCES ALL_OCCURRENCES}: will search for either declarations or
 *            references as specified above.
 *      </li>
 *       <li>All other fine grain constants defined in the <b>limitTo</b> category
 *            of the {@link IJavaSearchConstants} are also accepted nature:
