To perform a phrase search wrap the entire search phrase in quotes.

By putting double quotes around a set of words, you are telling vufind to consider the exact words in that exact order without any change.

To perform a single character wildcard search use the ? symbol.

For example, to search for "text" or "test" you can use the search:

te?t

To perform a multiple character, 0 or more, wildcard search use the * symbol.

For example, to search for test, tests or tester, you can use the search:

test*

You can also use the wildcard searches in the middle of a term.

te*t

Note: You cannot use a * or ? symbol as the first character of a search.

To perform a range search you can use the { } characters. For example to search for a term that starts with either A, B, or C:

{A TO C}

The same can be done with numeric fields such as the Year:

[2002 TO 2003]

To apply more value to a term, you can use the ^ character. For example, you can try the following search:

economics Keynes^5

Which will give more value to the term "Keynes"

Boolean operators allow terms to be combined with logic operators. The following operators are allowed: AND, +, OR, NOT and -.

Note: Boolean operators must be ALL CAPS

OR

The OR operator is the default conjunction operator. This means that if there is no Boolean operator between two terms, the OR operator is used. The OR operator links two terms and finds a matching record if either of the terms exist in a record.

To search for documents that contain either "economics Keynes" or just "Keynes" use the query:

"economics Keynes" Keynes

or

"economics Keynes" OR Keynes

AND

The AND operator matches records where both terms exist anywhere in the field of a record.

To search for records that contain "economics" and "Keynes" use the query:

"economics" AND "Keynes"

+

The "+" or required operator requires that the term after the "+" symbol exist somewhere in the field of a record.

To search for records that must contain "economics" and may contain "Keynes" use the query:

+economics Keynes

NOT

The NOT operator excludes records that contain the term after NOT.

To search for documents that contain "economics" but not "Keynes" use the query:

"economics" NOT "Keynes"

Note: The NOT operator cannot be used with just one term. For example, the following search will return no results:

NOT "economics"

-

The - or prohibit operator excludes documents that contain the term after the "-" symbol.

To search for documents that contain "economics" but not "Keynes" use the query:

"economics" -"Keynes"
