Only one link seems to be the problem. When you search using quotation marks "journal of treatment and prevention", we retrieve almost 3000 links with word "journal" in them. But not "treatment" or "prevention". All three terms should be found in each entry using this type of search. It seems to be only this title. We have tried other "journal of ......." titles with successful results. Why does only this link/title behave oddly? Thanks if you know how to fix this.
