To perform a single character wildcard search use the ? symbol.
For example, to search for "woman" or "women" you can use the search:

Tchaikovsky~0.8

Use the tilde ~ symbol at the end of a Multiple word Term. For example, to search for economics and keynes that are within 10 words apart:
"economics Keynes"~10
