The Single Layer tab offers a more elaborate search than the Substring Search tab. The first thing that is different from the Substring Search tab is that the Single Layer Search tab has a query history. Clicking the
and button makes the tab respectively go backward and forward one query.Furthermore, the tab offers different modes to restrict the search. The first mode lets you choose the form of the results. There are three options:
: the search string is part of or exact match in an annotation.
: each element of the search string (elements are divided by spaces) is part of or exact match in one of several consecutive annotations.
: each element of the search string (elements are divided by spaces) is part of or exact match in one of several consecutive tokens within one annotation.
The following mode offers the straightforward distinction between
and search. The third mode lets the user choose if the element of the first mode should contain the search string ( ), if the element should exactly match the search string ( ) or if some regular expression should be used in the match ( ).Finally, one can choose to restrict the search to one tier, a tier type or a participant.When you choose an N-gram to be the form of the result, you
can use two more options: a wildcard and a negation. The wildcard
takes the form of a #-sign. For instance, the search string
the # man
with the mode would return three annotations per
hit: the first annotation contains
the
(or exactly matches that, if
the mode is chosen), the
second annotation may contain anything due to the use of the
wildcard and the third annotation contains or exactly matches
man
. If the mode
is chosen, each
hit contains one annotation. In this annotation there is a N-gram
consisting of three tokens where the first token contains or exactly
matches the
, the second may be
anything and the third contains or exactly matches
man
.
If you want to find N-grams where a token matches anything but
one string, you can use the negation operator NOT(...), where you
can fill in the search string not to be matched on the dots. For
instance, the search string the NOT(strange)
man
would return 3-grams in same way as describe above,
but the hits where the second annotation or token matches
strange are left out.
