cleanCommon cleans too much

[alhoqbani]

Method cleanCommon performs str_replaceon the full string, without parsing the string into separate words.

This will remove stopwords from the string even if it was part of a word. For example, الأهل will be replaced with الأ because هل, which is part of the word, is a stopword.

It should use preg_replace to replace only fill words, or explode the string into array of words.
