Extended Search of Leibniz Universität Hannover

A search query is broken up into terms and operators. There are two types of terms: single terms and phrases. A single term is a single word such as »test« or »hello« A phrase is a group of words surrounded by double quotes such as »"hello world"«. For example, Use the search expression »"Fundamentals of electromagnetic energy conversion"« to reduce the result set. Note: If you are looking for hyphen words, use double quotes to minimize the search results for example: »"high-risk"«.

'?' -> Single character (matches a single character) - The search string »te?t« would match both 'test' and 'text'.
'*' -> Multiple characters (matches zero or more sequential characters) - »tes*« would match 'test', 'testing', and 'tester'. You can also use wildcard characters in the middle of a term. For example: 't*t' would match 'test', 'trust' and 'text'.

Boolean operators allow you to apply Boolean logic to queries, requiring the presence or absence of specific terms or conditions in fields in order to match documents. Examples: »"Oracle" OR "MYSQL"« or »"server apache" NOT "präsentation"«

The Search supports using parentheses to group clauses to form sub-queries. This can be very useful if you want to control the Boolean logic for a query. The query below searches for either "jakarta" or "apache" and "website": »(jakarta OR apache) AND website«

To search for a term similar in spelling to "roam," use the fuzzy search i.e. »roam~«. This search will match terms like roams, foam, and foams. It will also match the word "roam" itself.

To perform a proximity search, add the tilde character ~ and a numeric value to the end of a search phrase. For example, to search for "apache" and "jakarta" within 10 words of each other in a document, use the search: »"jakarta apache"~10«
