To refine results you can use your own queries. Expressions, operators and wildcats are available.

Expressions

Expressions are single words and phrases. The words/phrases you enter are case-insensitive. Single words are: Polish or courts. Phrases are groups of words in double quotation marks: "Polish courts".

Please note that the results will include only those entries in which the given phrase appears exactly as it is entered in quotation marks.

Logical operators

Multiple expressions combined with logical operators can be entered in the search field. The following logical operators can be used: OR, AND, NOT (in capital letters)

The OR  (alternative) operator combines two expressions and finds matching entries if either expression appears in the entry. The alternative symbol can be ||.

For example, to search for entries containing the phrases: Polish courts or jurisdiction, you can use: "Polish courts" jurisdiction or "Polish courts" OR jurisdiction or "Polish courts" || jurisdiction

Please note that OR is the default logical operator.

The AND operator (conjunction) used between expressions allows you to find entries where both expressions appear anywhere in the entry text. An alternative symbol can be &&.

For example, to search for entries containing the phrases "Polish courts" and "jurisdiction" you can use: "Polish courts" AND "jurisdiction"

The NOT (negation) operator excludes entries containing the expression entered after the operator. An alternative negation symbol can be !.

For example, if you want to search for an entry containing the phrase "Polish courts" but not "Federal court", you can use the query: "Polish courts" NOT "Federal court"

Wildcards

If you want to search for words which have different endings, you must use wildcards (?*) that represent any characters in the word.  

The * symbol means that there can be zero, one or more characters in that position in a particular expression.

For example, entering cert* would give results with words such as "certified", "certificate", "certificates", "certain". Entering co*t would give results with words such as "court", "concept", "contact".

If you want to search for words that differ by exactly one character, ? symbol is used.

For example, entering sta?e would give results of entries with words "state" "stage".

Please note that you cannot use the * or ? symbol at the beginning of a search word.
