Advanced Search in BIONDA

To access the advanced search the welcome page of BIONDA offers a direct link. Otherwise, the advanced search can also be reached from any other page via the header or footer.

Within the advanced search, the same database is reached as in the normal search. However, the advanced search is a more detailed search. The following figure shows the advanced search page.

Within a drop down menu, the user can choose seven different parameters:

• Disease
• Marker
• Author
• Jornal
• Year
• PMID
• Keywords

After choosing one parameter, the query is entered in the free text field. Here, alias names of potential biomarkers can be found. Moreover, it also finds subtexts, for lung cancer e.g intersititial lung cancer is found. In addition, it is possible to connect more than one search term with the three logical operators AND, OR and NOT. In case the user wants to search only one term, the default logical operator is “AND”. The operators can be chosen in a drop down menu, similar to the parameters. After entering one search term the user has to click the add button and it will be displayed in the text form below.

When the user want to delete the query, he can simply click on the CLEAR button and start from scratch. In this case, the user can also choose between abstract and sentence wise, the default here is sentence wise. If the query is ready, the search starts by clicking on the search button or by simply clicking the ENTER key.
