Enter all words that shall be found. As a standard all words must be contained by
a document. If only one or some of the words must be contained use the OR-Search
e. g. "insolvency OR debts". The case of characters will be ignored.
Overview Boolean Operators |
AND |
AND-Search, this is the initial setting |
OR |
OR-Search (inclusive-or, means: both ... and) |
Search expressions can be structured by parentheses:, e.g. "(debts AND
credit) OR insolvency".
Putting NOT before an expression (this can be a word, a phrase or a complex
expression in parentheses) will exclude records containing this expression from
the hits, e.g. "insolvency NOT London" excludes all records containing
both words.
Overview Functions |
NOT(word) |
word will be excluded from the hits |
EXACT(word) |
word will be found only if it corresponds exactly as written |
FUZZY(word) |
similar words will be shown even if the exact form is
found |
word |
if nothing else is specified the search will show both exact
and similar hits |
"strings of words" |
limiting a string of words with quotation marks will search for
the words in this order |
Words can be truncated by using "wild cards" or regular expressions.
"insur*" finds both insurance and insurancies.
Overview Regular Expressions |
* |
*suranc*, *versicherung, kredit*anstalt etc. The asterisk "*"
is used as place holder for a variable amount of characters - or
for no character |
? |
pe?ersen etc. The quotation mark "?" is used as place
holder for exactly one character. The example will find "Petersen"
"Pedersen" - but not "Peterson" - The latter
will be found by "Pe?ers?n" |
The "Search Area" where the search shall take place can be limited
by the use of particular functions.
Overview "Search Area" |
TITLE(word) |
word must be part of the document's title |
KEYWORD(word) |
word must be a keyword assigned to the document |
AUTHOR(word) |
word must be author of the document |
... |
Other Search Areas |
The "Expert Search" offers an easy way to use select the possible
"Search Areas" All Search Areas can be addressed directly by entering
the corresponding function.
Boolean Operators, Functions, Regular Expressions and Search Areas can be
combined with no limitations. |
