For a fuzzy search, use the tilde ("~") symbol at the end of a single word search term. For example, to search for a term similar in spelling to "roam," use the fuzzy search: roam~

~0. This does a fuzzy search with zero edits. 0 operations (insertions, deletions or substitutions of a single character; or transposition of two adjacent characters) are allowed to change a word into another. For example, the search term "Doe~0" will return results if and only if Doe exists in the records.
~1. This does a fuzzy search with one edit. 1 operation (insertion, deletion or substitution of a single character, or the transposition of two adjacent characters) is allowed to change a word into another. For example, the search term "Zo~1" will find terms like Zoe, Jo, So, or Ho.

This operator finds words that are a within a specific distance away. For example: "4007 9901"~2 will return 4007-5368-2997-9901 since 4007 and 9901 are separated by only 2 indexed terms (5368 and 2997).

This operator boosts precedence of the term in search. For example:

The && operator matches documents where both terms exist anywhere in the text of a single document. This is equivalent to an intersection using sets. For example:

The operators ||, OR, or a space between two terms have the same function. These operators link two terms and find a matching document if either of the terms exist in a document. This is equivalent to a union using sets. You must enclose the complete search string in parenthesis.

This operator requires that the term after the "+" symbol exist somewhere in the field of a single document.

The single character wildcard search looks for terms that match the term with a single character replaced.

The multiple character wildcard search looks for 0 or more characters.
