5.2 Advanced query processing

If you do not want to search the whole corpus, but just on a part of it, you can specify a corpus area. This feature is very useful for experimenting with queries. To specify a corpus area, open the Query Options window by clicking the corresponding toolbar icon or selecting the Search Options item in the Query menu of the TIGERSearch tool:

Figure: Query processing options

Now select one of the preselected search spaces or type in the search space using the syntax start-end. If you press the OK button, the defined search space will be saved for later processing. If you like to save the search space and immediately start query processing using the defined option, just click the Search button in the Query Options window.

Please note: After leaving the Query Options window, query processing using the search area option is only activated when clicking the Search with options toolbar icon or selecting the Search with options item in the Query menu. If you start query processing using the Search button, the defined search option will not be used.

If you do not want to view all matching corpus graphs, you can set an upper bound for the number of matching corpus graphs determined by the query processor. If you specify to search for n matching corpus graphs, query processing will be stopped automatically when n matching corpus graphs have been found. This option is also specified in the Query Options window.
