Advanced search info

You may search via typing words in the search box. Words in this box are considered as conneted via "OR". For eaxact phrases use quotes, e.g. "zee- en meerdijken". The wildcard is *, e.g. meerdijk*. A wildcard with a term with a space does not work "zee- en meerdijk"*  does not work. "meerdijk"* works. 

In order to limit the search field, a search class can be added in the search box. Search classes can be: creator (= author), contributor, subject (=keyword), publisher
For example classification:TPG* gives all hits with classification starting with TPG. Important: note that there is no blank betweeen : and the class (so classification: TPG* does not work). It also seems that this is case-sensitive (classification:tpg* does not work).

In case the search term consist of spaces and/or symbols, add quotes. So creator:Verhagen gives publication of various person with family name Verhagen, When you search a specific author, add initials and use quotes: creator:"Verhagen, H.J." In this case creator:Verhagen* and creator:"Verhage"* does not work, but  creator:"Verhagen"* works

At this moment project is not a searchable field.

The query line should look like:
or*&publisher=Deltares  (note that %3A is : and %22 is ")

"type" is always "report" in DiRK-Hydro, so it can be left blank.


Rijkswaterstaat no results
"Rijkswaterstaat"  all publishers with "Rijkswaterstaat" in the name, like "Rijkswaterstaat, DWW" and "Rijkswaterstaat COW"
Rijkswaterstaat, COW Only publishers with the exact name Rijkswaterstaat, COW
"Rijkswaterstaat, COW" Publishers with "Rijkswaterstaat, COW" in the name
