If you tick the box below the search field saying OR-search your hitlist will return all posts containing one or more of your search terms. If you use many search words in the OR-search the number of hits can be very large. But if your search terms are correct you should find the person or property you are looking for high on the hit list. This can be a useful way of searching in cases where a person has many names, such as Fridtjof Nansen's mother, Adeleide Johanne Thekla Isidora Nansen, f. Wedel Jarlsberg (Bøller from an earlier marriage), and it is uncertain which names are used in the different sources.
The hit list could be narrowed down if you are certain that some words should be included or excluded in the search.
The search words that you enter in the search field will be searched for independently of the sequence you have typed the words. The words will also be searched for in all fields, not only name fields, but the name fields are given a higher priority than the other fields, ranking hits in the name field higher than other hits.
