DocFetcher Pro 1.12 Release

DocFetcher Pro 1.12 has just been released. This release fixes a 7z- and a tar-archive-related crash, and brings dramatic performance improvements with respect to the handling of large indexes. The performance improvements were implemented partly in response to user feedback, and partly in preparation for the upcoming DocFetcher Pro Server, which will likely have to deal with much larger data sets than the current non-server version.

For some context: DocFetcher Pro is a full rewrite of the original DocFetcher, so under the hood they are actually two completely different programs. During the rewrite, the emphasis was on correctness and long-term maintainability, while performance was less of a concern. As a result, DocFetcher Pro used to be, up until now, generally slower than DocFetcher, although this difference in performance was not noticeable until you tried to index hundreds of thousands of files. When you did index that much data, the program would exhibit various kinds of slowness: It took forever to load indexes during startup, exiting the program became slow, and checking and unchecking folders in the Search Scope pane also became slow.

In the new 1.12 release, these performance issues were addressed with a major restructuring of some performance-critical code sections, numerous smaller code optimizations here and there, and an upgrade of the bundled Java runtime from Java 8 to Java 16. In a benchmark with an index comprising about 2.8 million files, these changes led to dramatic performance improvements, notably a reduction of index loading time from 63.048 s down to 8.726 s, which is a reduction down to about 14%, or 1/6. (Note: The two loading times are averages over 10 test runs each.) Other index-related operations are now also significantly faster.

DocFetcher Pro 1.11 Release

DocFetcher Pro 1.11 has just been released. The previously announced 7z v0.4 support is now implemented, meaning DocFetcher Pro can now read 7z archives created with the latest versions of 7-Zip.

In addition to 7z v0.4 support, an Outlook indexing crash has been fixed, and a --disable-auto-index-update launch parameter has been added. For details, see the changelog.

Some users have expressed dissatisfaction with DocFetcher Pro’s lack of a global hotkey, which in the Windows and Linux versions of DocFetcher can be pressed to bring the program window to the front. In DocFetcher Pro, this is in fact also possible, with the help of additional software. For details, see the question “Can you bring back the global hotkey from DocFetcher?” on the DocFetcher Pro FAQ.

With last week’s release of DocFetcher 1.1.24 and the addition of 7z v0.4 support, the next major item on the development agenda is now DocFetcher Pro Server. As stated before, this will be a huge undertaking, so it’s going to take quite a while, and furthermore, no reliable release date can be given at this time. That being said, it will probably be finished before the year is over.

DocFetcher Pro 1.10 Release

DocFetcher Pro 1.10 has just been released. This time, two problems were fixed: First, performance issues and a crash related to the preview pane line numbers that were introduced in the previous 1.9 release. And second, with type-ahead search enabled, phrase search and proximity search worked incorrectly when combined with wildcards. For details, see the changelog.

The development agenda posted earlier still applies.
