Trying to get "too specific" with limit queries either on the advanced search page or keyword / category search pages can easily mean you end up with a null result.   For example, a majority of annotations relate to Mary Baker Eddy, so running a limit query using "Mary Baker Eddy" with one or two other categories / keywords will probably yield several results. But only a few annotations relate to "Christian Science and Architecture" and fewer still relate to "Judaism and Christian Science." So a limit search for those two terms will not yield any results, since no annotations relate to both "Christian Science and Architecture" and "Judaism and Christian Science."   To find a very specific result, we suggest using the advanced search, starting by selecting just one or two categories (subjects, people, organizations, or controversies) and then adding your limiting factors one at a time.   Additionally, you can use the standard search function to look for several specific terms embedded in the annotation text itself using simple syntax (and, or).
