 # looqs: Release notes
+## 2022-07-29 - v0.5
+This release features multiple fixes and enhancements.
+
+It changes the database to drop an unused content column. Dropping it allows us
+to change to a contentless sqlite FTS index which frees up space.
+
+Upgrading might take a few seconds to a few minutes as looqs will recreate the whole index.
+How long this will take depends on the size of your database.
+
+The other major highlight is preview support for .odt files (unformatted, like plaintext).
+
+List of changes:
+
+ - General: As Ubuntu 21.10 is EOL, no looqs package will be provided for it any longer
+ - General: Update database scheme to drop unused content column and free up space
+ - General: Properly escape FTS arguments passed to sqlite to avoid query errors on some terms
+ - GUI: Fix double searches and results when explicit content search filters are provided
+ - GUI: Previews: Plaintext previews now obey scale selection too
+ - GUI: Previews: Begin basic, unformatted previews of .odt files
+ - GUI: Previews: Add file path below every preview for convenience (hovering unnecessary now).
+ - GUI: Previews: Fix bug causing an empty preview if a plaintext file started with a searched word
+ - GUI: Add menu option to open user manual
+ - GUI: Show progress dialog during database upgrade
+ - General: Correct error count in some conditions for failed paths
+ - General: Update user manual
+ - Minor improvements
+
+## 2022-06-29 - v0.4
+This release makes several minor improvements and begins prebuilt binaries of looqs that (should) run
+on any recent Linux distribution.
+
+ - General: Begin new, experimental distro-agnostic tarball containing prebuilt binaries and libs. See the README for more information.
+ - GUI: In the "Previews" tab, allow filtering by file, to only show previews for a specific file.
+ - GUI: Add "Show previews" context menu option to files in result (if available)
+ - General: Fix build with libquazip 1.X
+ - General: Properly report access errors as a failure during indexing
+ - GUI: Add button to export a list of all paths that failed
+ - General: Improve dir scan threading
+ - CLI: Improve helptext
+ - General: Add voidlinux build instructions

+### Prebuilt tarball (distro-agnostic) (EXPERIMENTAL)
+looqs is also distributed as a tarball containing prebuilt binaries and its library dependencies. The tarball is
+built using the Gentoo Hardened toolchain and the Qt version is smaller than what distributions usually
+include. It does not include libraries that should mess with fontrendering or the graphics stack. The binaries should run on any recent Linux distribution (requires glibc 2.34 or newer at least) and expects
+dependencies such as libGL to be provided by your distribution already (should be the case).
+
+It's considered experimental for two reasons. Firstly, looqs has no updater (yet). You will have to manually check for updates. Secondly, I can't guarantee that I'll be quick with updates of the tarball specifically if the library versions become outdated between looqs updates.
+
+You are therefore encouraged to use distro-native packages or to build it yourself if possible.
+
+The tarball can be obtained here: https://repo.quitesimple.org/tarball/looqs
+
+Quick start:
+
+```
+# Verify sig, see the end of this document: gpg --verify looqs-v0.4.tar.xz.sig
+tar xf looqs-v0.4.tar.xz # Replace with the actual version you have obtained
+cd looqs-v0.4
+./looqs-gui # or ./looqs for the CLI
+```
+
+An AppImage may accompany the tarball in the future.
+
+
 ### Other distros
 I'll probably add a package for voidlinux at some point and maybe will provide a Gentoo ebuild. However, I would appreciate help for others distros. If you create a package, let me know!

-As for distro-agnostic packages, I will also take a look into appimage / flatpak etc.  and/or maybe just provide a self-contained archive.

 ## Current Limitations and things to know
 You should be aware of the following:

- It may seem natural, but the GUI and CLI operate on the same database, so if you add files using the CLI, the GUI will search them too.
+- It may seem natural, but the GUI and CLI operate on the same database, so if you add files using the CLI, the GUI will know about them too.

 - If a file is listed in the "Search results" tab, it does not imply that a preview will be available in the "Previews" tab, as looqs can search more file formats than it can generate previews for currently.

- Database paths are stored inefficiently, not deduplicated to simplify queries. This may add up quickly. Also, each PDF text is stored twice. Each page separately + the whole document to simplify queries.
-To give you some idea: At the time this section was written, 167874 files were in my index. A FTS index was built for 14280 of those, of which 4146 were PDF documents. The PDFs take around 10GB storage space on the filesystem. All files for which an FTS has been built are around 7GB in size on the filesystem. The looqs database had a size of 1.6 GB.

- Existing files are considered modified when the mtime has changed. looqs currently does not check whether the content
-has changed.

 ## Config
-The config file is in `$HOME/.config/quitesimple.org/looqs.conf`. It will be created on first execution of the CLI or GUI

 ## GUI
-The GUI is minimal at this point. Depending on what you want to do, you may need to open the config file and change the settings there. Chances are that you may not need to do that.

 ### Configuring PDF viewer

 ## Tips

 ### Keeping index up to date
-The most obvious way is to use the GUI and add your favorite paths in the "Index" tab. Then occasionally, just rescan. This works for me personally, looqs quickly picks up new files. This however may not be good enough for some users.

 ## Query syntax / Search filters
 A number of search filters are available.

 | Filter (long) |  Filter (short) | Explanation |
 | ----------- | ----------- |----------- |
-| path.contains:(term) | p:(term) | Pretty much a SQL LIKE '%term%' conditions, just searches the path string |
+| path.contains:(term) | p:(term) | Pretty much a SQL LIKE '%term%' condition, just searches the path string |
 | path.ends:(term) | pe:(term) | Filters path ending with the specified term, e. g.: pe:(.ogg) |
 | path.begins:(term) | pb:(term) |  Filters path beginning with the specified term |
-| contains:(terms) | c:(terms) | ull-text search, also understands quotes | 
-
-Filters can be combined. The booleans AND and OR are supported. Negations can be applied too, except for c:(). 
-The AND boolean is implicit and thus entering it strictly optional. 
+| contains:(terms) | c:(terms) | Full-text search, also understands quotes |
+| limit:(integer) | - | Limits the number of results. The default is 1000. Say "limit:0" to see all results |
+Filters can be combined. The booleans AND and OR are supported. Negations can be applied too, except for c:(). Negations are specified with "!".

Albert S	e01f5d6490	shared: ParallelDirScanner: Perform first pass to collect paths Scan the top directory to collect paths for the threads. This way we don't launch threads for paths without subdirs. Secondly, large trees like usually $HOME will be scanned by multiple threads at first. Nevertheless, ParallelDirScanner can be improved still as threads may run quickly out of work, so we may end up with only one anyway again	2022-06-24 19:17:50 +02:00
Albert S	759d2a7924	Fix builds with quazip 1.X Sigh. quazip changed the lib name, include locations, etc. from version 1. Some distributions only have 0.9. Some only 1.x and so some packages break, so they simply patch it when building the package. Luckily, nothing we use from quazip is affected from an API perspective. So detect if there is quazip1, then use pkg-config to link that, else do it like before.	2022-06-21 22:33:50 +02:00
