Advanced search in DiVA is divided into one tab for ‘Research publications’ and one for ‘Student theses’.

Advanced search is also divided into two parts. This makes it possible to combine two (or more) different searches in a single list of search results, while it is also flexible in terms of which hits can be excluded from the list.

Below, we explain the various parts of the search form and give examples of how searches can be carried out.

Handling search blocks (AND, OR and NOT)

In every search block, AND is included between the fields it contains. For example, there is an AND between the field for language and the field for publication type.

Using the search blocks, it is possible to search in several different publication types that contain various fields.

For example, items with the ‘published’ status and reports lacking the ‘status’ field can be searched at the same time. Searching in one block gives only hits in published articles but no reports, since ‘report’ AND ‘published’ is not a possible combination.

You should therefor use two search blocks. Select ‘article’ as the publication type and ‘published’ as the status in the first block. Then add a new block by clicking on the OR button. Choose ‘report’ as the publication type in the new block. The results will then consist of published articles plus reports.

Free text searches

The majority of the search fields in DiVA are free-text fields.

A few examples of how free-text searches can be combined to limit or extend the search are given below.

 

 

Controlled searches

Controlled searches are done in the fields that have underlying authorised lists or given search parameters. In DiVA there are several fields of this kind, and some examples of fields of this type are given below:
