Tessmann allows you to query the document database directly
through the search bar, for more precise results and personalized
researches.
Search terms
Possible word inputs are distinguished into two main
elements
-
Sentences
A sentence is made up of terms enclosed in double
quotation marks and is regarded as a single term.
"Andres Hofer ist im Bozen geboren"
- returns only texts in which the phrase appears as it is with
only a space between the terms.
-
Single Words
A simple search term.
Andreas Hofer
- returns texts containing either Andreas or Hofer, with earlier
documents with both words.
Within a single search
term, you can use the special characters * e ? as
placeholders for unknown characters.
- Using the character ? will change the word by
one character
Te?t – returns documents
containing "Test" or "Text".
- Using the character * extends the word
indefinitely.
Boz* - returns any term
that begins with "Boz",such as Bozen or Bozner.
Logical search
You can use combinations of individual terms and phrases to
compose very complex queries.
All operators should be written in upper case
letters and possess the required number of terms, or they will
have no effect.
-
AND
The AND operator forces an inclusive search of at least two
terms, for example:
Andreas AND Hofer
– returns only the documents with both terms.
Andreas AND "Bozen Meran"
– returns only the documents with the first single term and the
whole sentence "Bozen Meran".
-
OR
The OR operator includes in the result set at least one of the
two terms.
Andreas OR Hofer
- returns pages with at least one occurence of "Andreas" or
"Hofer".
-
NOT
The NOT operator excludes the presence of the word next to it in
the result set.
Andreas NOT Hofer
– returns pages containing at least "Andreas" or only "Hofer".
NOT Hofer
– returns all the texts that do not contain the word "Hofer.
Search by distance
Tessmann Portal supports researches by approximation of
terms(Fuzzy Search) and words maximum distance in the text.
Fuzzy search
Approximates the word for the Levenshtein distance, or how
many changes, additions and reductions of letters are necessary in
order to go from the original word to the one found.
You can set this number by using the ~ character, with a
value ranging from 0.0 to 1.0, where 0.0 is the original word, and
1.0 is the maximum distance from that word.
Entering
Bozen~0.1
produces results such as Boxen, Boten and Noten
Distance between Terms
Tessmann Portal supports the search for words within a specific
distance. To perform a proximity search use the symbol
~,
but at the end of a
sentence.
For example, in order to search for "Bozen" and "Meran" within 10
words of each other in a document, type:
"Meran Bozen"~10
Search by priority
The search for priority allows to increase the importance of a
term over another. You can specify the priority of a term or
phrase using the ^, followed by a numerical value
indicating the priority.
For example, if you
want to see in the resulting documents the term Meran, with an
higher priority compared to Bozen, type
Meran^4 Bozen
- "Meran" has a priority 4 times higher than "Bozen".
The advanced search allows you to select documents for
metadata (title, year, name..), rather than for textual content.
At the moment you can query the following fields:
- Year of publication, using Y:
- with the standard format DD.MM.YYYY
- Publisher, using P: -
this option is possible only for books, for newspapers is
equivalent to the document name.
- Document name, using N:
- Type of pubblication, using T:
- At the moment values must be either "B", for books, or "Z", for
newspapers.
For example, entering
N:"Bozner Nachrichten"
will output all media named "Bozner Nachrichten".
It is important to notice that the text provided after :
must not contain spaces, or you will have to enclose it in double
quotes. It is always possible to use modifiers of terms and
sentences to get more general results (see Search
Terms for more details).
Y:02.05.1917
- returns all documents dated exactly 2 May 1915, while
Y:* 1917
or
Y:??.??.1917
- returns all documents from 1917.
Some examples of advanced combined queries
It is possible to combine all the above mentioned operators
to make requests of arbitrary complexity. Some examples are
reported here:
Andreas AND Bozen N:*1917 – returns all
documents containing both "Andreas" and "Bozen" from 1917."Andreas Hofer" AND Bozen AND T:Z AND
N:Dolomitten - returns only newspapers containing "Andreas
Hofer" and "Bozen" from the publisher "Dolomitten"."Kurhaus Meran"~20 OR "Waltherplatz
Bozen"~10 – returns all documents where or Meran Kurhaus and are
at a distance of up to 20 words, or Waltherplatz and Bozen are at
a maximum distance of 10 words, or both conditions at the same
time.
