The online search supports:

Stemming – Procedure that traces different variants of a word back to its root form
Fuzzy searching – advanced search technology enabling discovery of similar words in addition to exact matches of the search term
Wildcard searches – a wildcard character represents a single placeholder within a search term, allowing for more flexible results
Proximity searching – term analysis considering the distance between individual words within a query

For data import most metadata formats are accepted directly. In addition, we can create a custom-tailored import.
