To perform a fuzzy search use the tilde ~ symbol at the end of a single-word term.
For example the search roam~
will match terms like roams, foam, foams, etc
An optional distance parameter specifies the maximum number of edits allowed (between 0 and 2) defaulting to 2
For example Roam~1
will match roams and foam - but not foams since it has an edit distance of 2.
