"Contains phrase" in catalog search does not work consistently

[William C. Szwagiel]

Evergreen version 3.11.1

When performing a search in the catalog, if you set the "Matching" field to "Contains phrase," you do not appear to receive consistent results.

For example, if you set the "Catalog Field" to "Subject," and perform a search for "imaginary places," there are zero results.

However, if you search for "places" instead, you will receive results with "imaginary places" in a =650 subject field.

It seems to not like it when you use more than one word, but to my understanding, a phrase by definition is typically more than one word. Or does it mean something else in this context? And if it only means one word, what is the difference between "Contains phrase" and just "Contains"?

Adding a note that doing the same search as a keyword search works.

Also, using quotations for a subject search fails in the same way as using the "Contains phrase" search option.
