You can use it like that

  String strSelection = android.provider.CallLog.Calls.TYPE +
  " = " + CallLog.Calls.MISSED_TYPE+ 
  " OR " +  android.provider.CallLog.Calls.TYPE +
  " = " + CallLog.Calls.INCOMING_TYPE ;

Try this , this code i getting all documents files using media store, using single query with multiple arguments.

 String pdf = MimeTypeMap.getSingleton().getMimeTypeFromExtension("pdf");
    String doc = MimeTypeMap.getSingleton().getMimeTypeFromExtension("doc");
    String docx = MimeTypeMap.getSingleton().getMimeTypeFromExtension("docx");
    String xls = MimeTypeMap.getSingleton().getMimeTypeFromExtension("xls");
    String xlsx = MimeTypeMap.getSingleton().getMimeTypeFromExtension("xlsx");
    String ppt = MimeTypeMap.getSingleton().getMimeTypeFromExtension("ppt");
    String pptx = MimeTypeMap.getSingleton().getMimeTypeFromExtension("pptx");
    String txt = MimeTypeMap.getSingleton().getMimeTypeFromExtension("txt");
    String rtx = MimeTypeMap.getSingleton().getMimeTypeFromExtension("rtx");
    String rtf = MimeTypeMap.getSingleton().getMimeTypeFromExtension("rtf");
    String html = MimeTypeMap.getSingleton().getMimeTypeFromExtension("html");

    //Table
    Uri table = MediaStore.Files.getContentUri("external");
    //Column
    String[] column = {MediaStore.Files.FileColumns.DATA};
    //Where
    String where = MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?"
            +" OR " +MediaStore.Files.FileColumns.MIME_TYPE + "=?";
    //args
    String[] args = new String[]{pdf,doc,docx,xls,xlsx,ppt,pptx,txt,rtx,rtf,html};

    Cursor fileCursor = getActivity().getContentResolver().query(table, column, where, args, null);

    while (fileCursor.moveToNext()) {

    //your code

If you want to use the built-in optimization in the Android SQLite connection you could do something like this instead:

String table = "CONTACT_TAGS";
String[] columns = {"_id"};
String where = "TAG1=? OR TAG2=? OR TAG3=? OR TAG4=? OR TAG5=?";
String[] args = {"tagname", "tagname", "tagname", "tagname", "tagname"};

SQLiteDatabase db = myDatabaseHelper.getReadableDatabase();
Cursor cursor = db.query(table, columns, where, args, null, null, null);

The difference from @raultum's solution is that you let the database connector decide how to interpret the submitted data. This is extra interesting from a security perspective.

Try something like that..

SQLiteDatabase db = YourDatabaseHelper.getReadableDatabase();
String TABLE = "CONTACT_TAGS";
String[] FIELDS = { "_id" };
String WHERE =  "TAG1='tagname' OR TAG2='tagname' OR TAG3='tagname' OR TAG4='tagname' OR TAG5='tagname' ";
// Execute
cursor = db.query(TABLE, FIELDS, WHERE, null, null, null, null);

If you read the documentation of the Cursor.query() method you find the definition for selection as follows:

selection: A filter declaring which rows to return, formatted as an SQL WHERE clause (excluding the WHERE itself). Passing null will return all rows for the given table.
