Advanced Search

Here you will find some tips about how you could perform an advanced search

* Wildcard Searches

The search engine supports single and multiple character wildcard searches within single terms (not within phrase queries).
To perform a single character wildcard search use the "?" symbol.
To perform a multiple character wildcard search use the "*" symbol.

The single character wildcard search looks for terms that match that with the single character replaced. For example, to search for "text" or "test" you can use the search:

te?t
Multiple character wildcard searches looks for 0 or more characters. For example, to search for test, tests or tester, you can use the search:

test*
You can also use the wildcard searches in the middle of a term.

te*t
Note: You cannot use a * or ? symbol as the first character of a search.

* Boolean Operators

Boolean operators allow terms to be combined through logic operators. The search engine supports AND, "+", OR, NOT and "-" as Boolean operators(Note: Boolean operators must be ALL CAPS).

OR

The OR operator is the default conjunction operator. This means that if there is no Boolean operator between two terms, the OR operator is used. The OR operator links two terms and finds a matching document if either of the terms exist in a document. This is equivalent to a union using sets. The symbol || can be used in place of the word OR.

To search for documents that contain either "DIGIPASS Pack" or just "DIGIPASS" use the query:

"DIGIPASS Pack" DIGIPASS
or

"DIGIPASS Pack" OR DIGIPASS

AND

The AND operator matches documents where both terms exist anywhere in the text of a single document. This is equivalent to an intersection using sets. The symbol && can be used in place of the word AND.

To search for documents that contain "DIGIPASS Pack" and "authentication" use the query:

"DIGIPASS Pack" AND "authentication"

+

The "+" or required operator requires that the term after the "+" symbol exist somewhere in a the field of a single document.

To search for documents that must contain "DIGIPASS" and may contain "authentication" use the query:

+DIGIPASS authentication

NOT

The NOT operator excludes documents that contain the term after NOT. This is equivalent to a difference using sets. The symbol ! can be used in place of the word NOT.

To search for documents that contain "DIGIPASS Pack" but not "authentication" use the query:

"DIGIPASS Pack" NOT "authentication"
Note: The NOT operator cannot be used with just one term. For example, the following search will return no results:

NOT "DIGIPASS Pack"
