In the "specific" search, you can type a phrase and enclose it in inverted commas so that the term you are looking for is specifically located. In this same method, you can also search for +Leviathan +Calus, and you will find all the records that have both words. You can also search for +Leviathan -Calus, and you will find all the records that have the word Leviathan but that do not have the word Calus. In this type, the content is not sorted by relevance, it returns everything that fits your search.
In the search type "generalized", the order in which the content is displayed is relevant according to what you search for. This method ignores words with less than 4 letters because they are very common; however, when searching for a term, the system will return an order that is most relevant to what was searched until the least relevant.
Remembering that you can share the search link with other friends for both methods so they can have the same vision that you are having. To do this, use the share buttons or copy the URL of the page after searching.
