General Help - zbMATH Open
For searching in zbMATH Open you may employ the multi-line search for documents, authors, serials or software respectively. It offers a convenient form optimized for ease of use. The one-line search on the other hand allows for free logical combinations of all available search fields (see the list of operators) and is much more flexible.
Multi-Line Search
The default search on zbMATH Open is the multi-line search. Simply select the appropriate search field, enter your search terms and link them with the Boolean operators (AND, AND NOT, OR). If you enter several search terms in a search field, they are automatically linked with the AND operator. The Boolean operators are evaluated in order, i.e. from top to bottom.
One-Line Search
In the following you will find a short explanation of available search fields. A simple search query without any specified field results in an anywhere search, which takes into account the fields listed under the heading "any".
List of operators
| a & b | Logical and (default) |
| a | b | Logical or |
| !ab | Logical not |
| abc* | Right wildcard |
| "ab c" | Phrase |
| (ab c) | Term grouping |
Examples
There are various examples of typical one-line searches in each search facet (button "Help"). A very simple example is the following: au:Hardy Ramanujan ti:asymptotic
Documents search
Use the Documents search to find documents on specific topics, by title or other characteristics. To find all publications by a specific author or from a specific journal you should instead use the respective search tab.
