If I search on "glass", the results page offers the queried results and additional pages via pagination (1,2...NEXT) at the bottom of the page. My trouble is I get a 404 error if I search "clear glass" and then click next or page #2 etc... The "space" between the term "clear" and "glass" is removed, as displayed is the search form, upon clicking additional pages.
Pagination performs if I use only "glass" in my search.
If i put a "-" dash between "clear" and "glass", pagination works.
Any ideas would be much appreciated. Trying to understand.
