 ## Search
 
 Usage:
 
-> [!NOTE]
-> Search uses a different executable (`clg`) than compression (`clp`).

 ```shell

 ```
 
 * `archives-dir` is a directory containing archives.
 * `wildcard-query` is a wildcard query where:
     * the `*` wildcard matches 0 or more characters;
     * the `?` wildcard matches any single character.
 * `options` allow you to specify things like a time-range filter.

+    * For a complete list, run `./glt s --help`
+
+> [!TIP]
+> Adding spaces (when possible) at the begin and the end of the wildcard-query can improve GLT's search performance,
+> as GLT doesn't need to consider implicit wildcards during query processing.
+> For example, the query " ERROR * container " is preferred to "ERROR * container".

+## `make-dictionaries-readable`
+
+To convert the dictionaries of an individual archive into a human-readable form, you can use
+`make-dictionaries-readable`.
 
-* `clp-s` currently only supports *valid* ndjson logs; it does not handle ndjson logs with trailing
-  commas or other JSON syntax errors.
-* Time zone information is not preserved.
-* The order of log events is not preserved.
-* The input directory structure is not preserved and during decompression all files are written to
-  the same file.
+```shell
+./make-dictionaries-readable archive-path <output dir>
+```
+
+* `archive-path` is a path to a specific archive (inside `archives-dir`)
+
+See the `make-dictionaries-readable`
+[README](../../components/core/src/clp/make_dictionaries_readable/README.md) for details on the
+output format.
