nuzecast discovered a bug in search engine, that does not ignore "common" words during search (words such as "the", "are", "by", etc). The bug seems only affect english language pack that comes with 4images.
The bug is actually not in the code, but in misspelling the file with stop terms list.
The fix is simple - rename:
lang/english/
stop_searchterms.txtto this:
lang/english/
search_stopterms.txt
