Single Term: Matches a single word. The term hello would match ALL documents containing the word hello. Phrase: Matches ALL multiple words. The term "hello world" would match ALL documents containing both hello AND world.

Multiple Term: Matches ANY of multiple words. For instance, hello world would find all documents containing hello OR world.

Single Character: The single character wildcard search looks for terms that match that with the single character replaced. For example, to search for text or test you can use the search: te?t.

Multiple Character: Multiple character wildcard searches looks for 0 or more characters. For example, to search for test, tests or tester, you can use the search: test*.

Fuzzy Search: To do a fuzzy search use the tilde, "~", symbol at the end of a Single word Term. For example, to search for a term similar in spelling to "roam" use the fuzzy search: roam~. Required Term Search: The "+" or required operator requires that the term after the "+" symbol exist somewhere in a the field of a single document. To search for documents that must contain "hello" and may contain "world" use the query: +hello world.

Proximity Search: To do a proximity search use the tilde, "~", symbol at the end of a Phrase. For example to search for a "hello" and "world" within 10 words of each other in a document use the search:: "hello world"~10. Exclusion Term Search The NOT operator excludes documents that contain the term after NOT. This is equivalent to a difference using sets. The symbol ! can be used in place of the word NOT. To search for documents that contain "hello" but not "worl" use the query: hello NOT world or hello !world
