Search tips

You can enter multiple search terms to get better search results. To search even more precisely, you have the following options.

"..."

Quotations "..." can be used to search for sentences. For example, if you enter "Boolean algebra", a search will be made for sentences that literally contain this.

+

Words starting with a '+' must appear in the items. If you search for multiple search terms, and one of them is '+project', you will find search results that contain the word 'project', sorted by how many of the other search terms they contain.

-

Words starting with a '-' may not appear in the items. So if you search for multiple search terms and one of them is '-project', you will find search results that contain one or more of the other search terms and not the word 'project'.

*

By searching for words ending in '*' you will find all combinations with that word. For example, if you enter 'change*' you will get 'change' as well as 'changed' and 'changes'.
