Simple search broken when word "of" is present

[jploski]

In EPrints 3.3.12 the simple search feature (using the internal search plugin) will in most cases return no results when the search string contains the word "of" because this word is only looked up in creators_name, then ANDed with all the other search conditions.

I'm posting it mostly for documentation purposes because this issue is apparently already fixed in the Git repository by the following commit:

72d31b9

Another workaround (not needed with the patch) would be to add "of"=>1 to freetext_stop_words in cfg.d/indexing.pl.
