To perform a single character wildcard search use the ? symbol.
For example, to search for "Bruegel" or "Brueghel," you can use the search:
Brueg?el
The ? symbol can also be used for variant spelling.
For example, to search for both the American spelling “armor” and the British spelling “armour,” you can use the search:
armo?r
To perform a multiple character, 0 or more, wildcard search use the * symbol.
For example, to search for costume, costumes or costumer, you can use the search:
costume*
You can also use the wildcard searches in the middle of a term.
cost*me
Note: You cannot use a * or ? symbol as the first character of a search.
Use the tilde ~ symbol at the end of a Single word Term. For example, to search for variant spellings of "catalog," use the fuzzy search:
catalog~
An additional parameter can specify the required similarity. The value is between 0 and 1, with a value closer to 1 only terms with a higher similarity will be matched. For example:
catalog~0.8
The default that is used if the parameter is not given is 0.5.
Use the tilde ~ symbol at the end of a Multiple word Term. For example, to search for duchamp and exhibitions that are within 10 words apart:
"duchamp exhibitions"~10
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:
Warhol photography^5
Which will give more value to the term "photography"
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. Search terms themselves can be in either lowercase or uppercase letters. For example, a search for furniture will find matches for furniture, Furniture and FURNITURE.
The AND operator is the default conjunction operator. This means that if there is no Boolean operator between two terms, the AND operator is used. The AND operator matches records where both terms exist anywhere in the field of a record.
To search for records that contain "dali" and "surrealism" use the query:
dali surrealism
or
dali AND surrealism
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 "dali" and may contain "surrealism" use the query:
+dali surrealism
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 "Dali surrealism" or just "surrealism," use the query:
"dali surrealism" OR surrealism
The NOT operator excludes records that contain the term after NOT.
To search for documents that contain "surrealist/surrealism" but not "Dali" use the query:
(surrealist OR surrealism) NOT Dali
Note: The NOT operator cannot be used with just one term. For example, the following search will return no results:
NOT Dali
The - or prohibit operator excludes documents that contain the term after the "-" symbol.
To search for documents that contain "surrealism" but not "Dali" use the query:
surrealism -Dali
