Unlike other search parameters, morelike is only working alone. Morelike already creates a unique morelike area comparable in usefulness to a category or a subject outline, but it gives many many more pages, and they're of unspecified characteristics. A morelike area might find new use as a stepping-off point targeting title, template, category, file, and other page characteristics in that unique area of interest. Also, this singular-standalone trait is awkward to try to rationalize in Search documentation.

The cool things about morelike areas is that they're not manual, and they're not biased. Compared to categories and outlines, morelike areas are more complete; they list missing and orphaned articles. They're easier; they are not hampered by the problems of of subcategories (T37402), and input pagenames (finding category pagenames, and outline pagenames). The area of interest is definitely fast to create, just not subsequently workable like it is with incategory.

A workaround for wikiprojects or a user with there own unique area of interest is to cut and paste a large, reference-set of words into the query box, and then filter this with other search parameters to get the desired a meaningful page count and reusable search link.

The need was raised at the Wikipedia help desk.
