常见的搜索方法：

// select * from contacts

调用方式：

        readContacts();

        getFuzzyQueryByName("av");

        getPeople("138");

以下方法可以称是万能查询，  如联系人有“张三”，“张4”,“郑源”，“zhong wei”,  

输入“张”， 可以查询出 {“张三”， “张4”}

输入“z”, 可以查询出{“张三”，“张4”,“郑源”，“zhong wei”}

输入"zy" , 可以查询出{"郑源"}

输入电话号码， 也可以正确查出结果。

Cursor cursor = searchContact(this, "zy");
while(cursor.moveToNext()){

Log.i(TAG, "name: " + cursor.getString(0));
Log.i(TAG, "NUMBER: " + cursor.getString(1));
Log.i(TAG, "TYPE: " + cursor.getString(2));
Log.i(TAG, "LABEL: " + cursor.getString(3));
Log.i(TAG, "CONTACT_ID: " + cursor.getString(4));
Log.i(TAG, "_ID: " + cursor.getString(5));
Log.i(TAG, "PHOTO_THUMBNAIL_URI: " + cursor.getString(6));
Log.i(TAG, "DISPLAY_NAME_SOURCE: " + cursor.getString(7));
Log.i(TAG, "-------------------------------");
}

cursor.close();

}

public Cursor searchContact(Context ctxt, CharSequence constraint) {
