When an object has its title in double quotes (e.g. "unser dorf hat zukunft") AND the title contains words that are included on stopwords.txt (e.g. unser, hat), search returns no results.

Steps to reproduce:

1. Create a new article with title "Unser Dorf hat Zukunft" (double quotes included);
2. Modify stopwords.txt and add two new entries, "unser" and "hat";
3. Restart SOLR and then re-index it. SOLR has to be restarted, re-indexing alone will not activate modifications;
4. Results:

unser dorf hat Zukunft : NOT found (issue)
"unser dorf hat Zukunft" : found (expected behaviour)
dorf hat Zukunft : found (expected behaviour)
unser dorf Zukunft : found (expected behaviour)
unser : NOT found (expected behaviour, as this is a keyword listed in stopwords.txt)
hat : NOT found (ditto)
