Helpful Searching Tips

Wildcard Searches

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

For example, to search for "woman" or "women" you can use the search:

wom?n

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.

Fuzzy Searches

Use the tilde ~ symbol at the end of a Single word Term. For example, to search for variant spellings of "Tchaikovsky," use the fuzzy search:

Tchaikovsky~

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:

Tchaikovsky~0.8

The default that is used if the parameter is not given is 0.5.

Proximity Searches

Use the tilde ~ symbol at the end of a Multiple word Term. For example, to search for economics and keynes that are within 10 words apart:

"economics Keynes"~10
Range Searches

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]
Boosting a Term

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

Boolean operators allow terms to be combined with logic operators. The following operators are allowed: AND, +, OR
