Pausing and resuming indexing is possible in both DocFetcher Pro and DocFetcher Server, but the functionality is somewhat non-obvious: Just abort the current indexing process. In the case of index creation and index rebuilding, you'll then be asked whether to keep or discard the partially created index. Select \\"keep\\". When you want to resume indexing, select that partial index and run an index update on it. It may take some time for the application to find the spot where indexing was aborted previously.
