Chapter 3. TROVA: Contents search
If you want to perform a detailed search over multiple you can use the annotation content search. This allows you to restrict the search to certain tiers, to use regular expressions, etc. while examining multiple annotation files at once.
To include multiple files in the search domain, select one or more nodes in the tree-view of the by clicking on the nodes while holding down the CTRL key on the keyboard. If you right click one of the selected nodes and select , you include all annotation files under the selected corpus nodes in the search domain. Alternatively, you can select a parent node, in which case all the daugther nodes will be included in the search.
A new browser frame for the search engine will appear with the search domain displayed at the top of each of the three search tabs:
The domain shows the name of selected node in the archive and all types of annotation files in the domain of that node. You can include or exclude types of annotation files in the search by respectively checking or unchecking them. In this case we have only one type of annotations: EAF files (3 EAF files).
It is possible that you are not allowed to read files from part of the domain due to (http://www.lat-mpi.eu/tools/ams/). In that case all searchable files from that part are excluded from the annotation content search. As a result the search domain contains less files. Compare for instance the two shots in figure 3.3. The domain is the same in both figures: . However, because resources in part of the domain are not readable for the user, the number of files to be searched differs. In the upper frame user had with more rights had access to more files, while in the lowe part of the screenshot, we see that a user with less rights can access fewer files.
As can be seen from figure 3.3 there are three tabs offering different kinds of search:
: finds all annotations in which the search string occurs.
: finds all annotations or N-grams in which the search string or regular expression occurs, both case sensitive and insensitive and possibly restricted to one (type of) tier.
: finds annotations in three related tiers. You can use multiple search strings and regular expression and make constraints on duration and time slot as well as constraints on how the search strings are to be combined.
