The search box at the top of the page offers a number of different search types. You may search on "content" or on "conferences" or on "companies" or on "people" etc.
A search on "content" will generate matches from amongst all content types. You may then click on specific tabs (e.g. articles & white papers) to filter your results further.
Spelling does not have to be exact as we use a "fuzzy" search. However, if you wish to search for an exact term, you should place your search term within speech marks. For instance, if you are searching for people called "Andrews", and you do not want people named "Andrew" to appear, then place the word "Andrews" within speech marks.
If you enter two keywords, this will search for posts containing BOTH words.
