;base set:Select the base set in which to search. This is set the root element (/) by default.
Select which sets from the current DataSet should be searched.
;audioset search expression:Select which audio sets to search by specifying, for example, the sampling rate (SR:==:44100).
 
;segment range:Select a segment or time range in which to search. For example, specifying ''inside'' and ''0s_120s'' would only search in the first 120 seconds of the signal.
empty list before search
;segment length:Limit search according to segment length.
 
;segment search expression:Select attributes by which to filter the search results. E.g. you could look for all segments with the text 'beautiful' by entering ''Text:=I:beautiful''.
Empty the segment list before searching. Otherwise segments which were previously in the list, but are no longer in the search criteria remain in the list.
;empty list:If checked, the list is emptied before the search begins. Otherwise, the search results are appended to the current segment list.
 
audio set type
 
Choose from the following
 
Logically, if you have selected soundfiles in the 'select search sets' option and choose only audio 'sequences', no segments will be found.
 
audio set ID
 
Specify which sets should be searched. Wildcards are allowed.
 
ID
 
Limit the search to a subset of segment IDs. Wildcards are allowed. The default is all segment IDs '*'.
 
ch.
 
Limit the search to a particular channel or choose all for all channels.
 
length
 
Limit the search to segments with a length longer or shorter than the value below. The default length is 1s (1 second). The length can also be given in samples (e.g. 41000 for a 1 second length at a sampling rate of 41000). See Specifying Signal Segments for more formatting details.
 
range
 
Limit the range within which to search for segments. Note that this range will be the same for all soundfiles defined in the search set. See Specifying Signal Segments for more details.
 
mode
 
Select if all the criteria below must be matched (logical and) or any one of them must be matched (logical or).
 
select attributes
 
Select the user-defined attributes from those existing in the search set. Note that the Select Attributes dialog searches through the DataSet for existing attributes and this can take some time. If you already know the name of the attribute you want to search for, just type it into the Name field below.
 
Name
 
The name of the attribute to match. Note that an attribute may only be specified once (e.g. you are not allowed to search for IDs which are like '<code>pattern1</code>' and IDs which are like '<code>pattern2</code>'.
 
Cond.
 
The condition for the attribute/value match. See conditions.

The Find Segments dialog is used to populate a segment list with segments from the current project. It is therefore only available if the selected element in the Overview is a segment list. You can open the Find Segments dialog with the hotkey F3.

audioset type
Search for segments in either sound files, sequences or both (all).
base set
Select the base set in which to search. This is set the root element (/) by default.
audioset search expression
Select which audio sets to search by specifying, for example, the sampling rate (SR:==:44100).
segment range
Select a segment or time range in which to search. For example, specifying inside and 0s_120s would only search in the first 120 seconds of the signal.
segment length
Limit search according to segment length.
segment search expression
Select attributes by which to filter the search results. E.g. you could look for all segments with the text 'beautiful' by entering Text:=I:beautiful.
empty list
If checked, the list is emptied before the search begins. Otherwise, the search results are appended to the current segment list.
