Need Help With Search Query

[jepler]

If I build a search query similar to this:

"SELECT DISTINCT object_id,object_title,object_description
WHERE MATCH (object_id,object_title,object_description)
AGAINST ('$keyword_search' IN BOOLEAN MODE)";

will it return both numeric and alpha matched results? In other words, I would
like for the following result to be returned if someone types either "11.4" or "geography" in the
keyword search field on my Web page.

11.4 Curriculum Guide Standard IIA 5 Themes of Geography
