Removing some English token words (such as “are” or “or” etc.) from the system stoplist of full text search?
You can turn off the system stoplist and create your own, eg

ALTER FULLTEXT INDEX ON dbo.yourTable SET STOPLIST = OFF

CREATE FULLTEXT STOPLIST myCustomStoplist;

ALTER FULLTEXT STOPLIST myCustomStoplist ADD 'someWord' LANGUAGE 'English';

ALTER FULLTEXT INDEX ON dbo.yourTable SET STOPLIST = myCustomStoplist


If you create an empty stoplist, it means all words are considered, or to put it another way, words that were previously considered noise words are no longer.  You will need to add some words to avoid index bloat, and as mentioned in my other post, if you really leave the word 'a' out of your stoplist, searches for 'a' will return most of your documents, somewhat defeating the object of full-text index ( ie tightly scoped searches ).
