Here is one:
There is a page called Rooms Guide. The first heading says “Classrooms Guide”. It has comments embedded that say classroom several ways, several times. Searching for this using the phrase “classroom” or “Classroom” or “Class Room” all return fairly poor results (Not in the first page). By contrast, searching using google: “classrooms site:dallasmakerspace.org/wiki” and it is the 6th return.
Here is a discussion of this topic:
It includes (or links to) this example:
search for any financial form, of which you know the file name, e.g. “FORM : Dallas Makerspace Receipt of Sale” and nothing will be found, even if you use the file search.
There may be others gleaned from that discussion as well.
