Search terms
Choosing the right search terms is the key to finding the information you need.
Start with the obvious – if you're looking for general information on F.W. de Klerk, try de klerk.
But it's often advisable to use multiple search terms; if you’re looking for information on de Klerk that is relevant to the National Party, you’ll do better with de klerk national party. And F.W. de klerk national party may produce even better results
Case sensitivity
ARCA searches are NOT case sensitive. For example, searches for de klerk, DE KLERK and De KlErK will all return the same results. All letters, regardless of their case are seen as lower case.
Automatic "and"
By default, the ARCA search will return records that include all of your search terms. There are no need to include "and" between terms.
Optional and automatically excluded words
ARCA returns records that include all of the words that were used in the search, but some words called "stopwords" are automatically removed from the search Very common words, such as "the," "and," or "of," are usually dropped from searches because they typically don't convey much information compared to the other words in a search. Generally, excluding common words allows us to return better search results. If one of these words is important to your search, you can precede it with a plus sign "+" to ensure that it is required to appear in every search result. So, for example, a search for +The National Party will return only results that include the word "the."
Phrase searches
Sometimes you'll only want results that include an exact phrase. In this case, simply put quotation marks around your search terms. Phrase searches are particularly effective if you're searching for proper names ("F.W. De Klerk").
Negative terms
If a word or phrase has multiple meanings, you can remove it from the search by putting a minus or an "AND NOT" before the word or phrase(de klerk and not "national party").
