Error with distributed index

[kuryha]

If you use the distributed index, you can get the following error:
Searching index "alias_index_name" for "sphinx_search_string" failed with error "distributed index 'index_name' in multi-index query found

As I understand, it occurs because of excess whitespace in request in Verdet/SphinxSearchBundle/Services/Search/SphinxSearch.php:151:

        $indexNames = '';
        foreach ($indexes as &$label) {
            if (isset($this->indexes[$label])) {
                $indexNames .= $this->indexes[$label] . ' ';
            }
        }

To solve this problem, after above code, i use trim:

        $indexNames = trim($indexNames);

Can you change the code?
