Boolean Expressions🔗

developer java OR .net
Perl AND C++ NOT Java

The query language has a limited support for commonly used Boolean expressions. The above examples are interpreted as expected, respectively searching for a document mentioning the keywords 'developer' and either 'java' or '.net', and a document mentioning the keywords 'Perl' and 'C++' but not the keyword 'Java'.

Boolean operators are only interpreted in simple full-text queries. If the query contains any other above mentioned query syntax, such as field names or condition operators, boolean operators won't be recognized.
