Wildcard searches

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

te?t will match “test” or “text.”

To perform a multiple character wildcard search use the * symbol.

test* will match “test,” “tests,” or “testing.”

Fuzzy Searches

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~. This search will find terms like foam and roams.

To perform a multiple character wildcard search use the * symbol.

You can adjust the degree of fuzziness by adding a value between 0 and 1. For example: roam~0.8. The default is 0.5.

Proximity Searches

To do a proximity search use the tilde, ~, symbol at the end of a Phrase.

For example the query "George Bush"~2 will find “George W. Bush” and “George Herbert Walker Bush.”

Boosting a Term

To boost a term use the caret, ^, symbol with a boost factor (a number) at the end of the term you are searching. The higher the boost factor, the more weight it will have in the search.

For example, searching for Iraq^4 allegations would give “Iraq” four times as much weight in the search as “allegations”.
