+## Usage
+
+Once you have configured one or more (and marked one as the default,
+see above) elasticsearch clusters, you can start using `esctl`. Since
+there are just too many things you can do with it, we'll just outline
+a couple of examples here.
+
+To see the status of a cluster:
+
+```console
+$ esctl cluster status 
+DEFAULT                    STATUS                 
+Cluster Name               eck-cluster-dev-s1
+ES Status                  green

+```console

+indices.recovery.max_bytes_per_sec              320mb

+
+Settings can be changed, use json path to specify a setting:
+
+```console
+$ esctl cluster settings set indices.recovery.max_bytes_per_sec:480mb
+```
+
+Searching is pretty easy. First check which indices exist:
+
+```console
+$ esctl index ls

+```
+
+Like a dataview in kibana you can specify an index pattern for search:
+
+```console
+$ esctl search -i foo*
+{"id":"1779873299", "score":1.0000, "index":"foo2", "source":{"message":"foo bar"}}{"id":"1779870997", "score":1.0000, "index":"foo2", "source":{"message":"start","time":"27.05.2026T10:55:33+0200","title":"zeitbuchung"}}{"id":"1779870750", "score":1.0000, "index":"foo2", "source":{"message":"pause","time":"27.05.2026T10:33:45+0200","title":"zeitbuchung"}}{"id":"1779870103", "score":1.0000, "index":"foo2", "source":{"message":"punktlich gebucht","time":"27.05.2026T10:20:01+0200","title":"zeitbuchuung"}}{"id":"1779432806", "score":1.0000, "index":"foo2", "source":{"message":"strange compound 2"}}{"id":"1779432750", "score":1.0000, "index":"foo2", "source":{"message":"strange compound 1"}}{"id":"1778600947", "score":1.0000, "index":"foo2", "source":{"id":"d8d8d","user":"scip"}}{"id":"1778600945", "score":1.0000, "index":"foo2", "source":{"id":"d8d8d","user":"scip"}}{"id":"1778600857", "score":1.0000, "index":"foo2", "source":{"id":"d8d8d","user":"scip"}}{"id":"1778601788", "score":1.0000, "index":"foo2", "source":{"id":"new1","message":"live long and prosper"}}{"id":"1778601422", "score":1.0000, "index":"foo2", "source":{"id":"new1","message":"love long and prosper"}}{"id":"1779447242", "score":1.0000, "index":"foo2", "source":{"message":"australian thai","title":"curry in a hurry"}}{"id":"1779447284", "score":1.0000, "index":"foo2", "source":{"message":"german killer food","title":"wuerger burger"}}{"id":"1779364394", "score":1.0000, "index":"foo2", "source":{"id":"1","message":"non-dead human looks curious at TargetOne"}}
+```
+
+Oops, that looks gibberish. It's because `esctl` just prints the raw
+JSON search results. There are multiple ways to post-process them:
+
+You can use `jq` (here, we're using `-l 1` to limit the output to 1 document):
+
+```console
+$ esctl search -i foo* -l 1 | jq
+{
+  "id": "1779364394",
+  "score": 1.0000,
+  "index": "foo2",
+  "source": {
+    "id": "1",
+    "message": "non-dead human looks curious at TargetOne"
+  }
+}
+```
+
+However, you might as well use internal filtering using jsonpaths:
+
+```console
+$ esctl search -i foo* -l 1 -p source.message
+non-dead human looks curious at TargetOne
+```
+
+To get more help about internal jsonpath filtering, run `esctl
+help-jsonpath`.
+
+A full text search looks like this:
+
+```console
+$ esctl search -i foo* thai | jq
+{
+  "id": "1779447242",
+  "score": 2.3842,
+  "index": "foo2",
+  "source": {
+    "message": "australian thai",
+    "title": "curry in a hurry"
+  }
+}
+```
+
+Instead of a costly full text you might as well specify the field to
+search within:
+
+```console
+$ esctl search -i foo* message=thai  | jq
+{
+  "id": "1779447242",
+  "score": 2.3842,
+  "index": "foo2",
+  "source": {
+    "message": "australian thai",
+    "title": "curry in a hurry"
+  }
+}
+```
+
+Of course you can search for multiple fields (or multiple terms in
+full text search). By default search terms are applied using logical
+AND, which you can change with the option `--or`.
+
+You can also change the sorting (`--sort-by`) and the time range
+(`--timerange`).
+
+To further narrow down search results you can add filters, which must
+match literally:
+
+```console
+$ esctl search -i foo* -F title=zeitbuchung message=pause | jq
+{
+  "id": "1779870750",
+  "score": 2.8426,
+  "index": "foo2",
+  "source": {
+    "message": "pause",
+    "time": "27.05.2026T10:33:45+0200",
+    "title": "zeitbuchung"
+  }
+}
+```
+
+To check which field mappings are available for an index:
+```console
+$ esctl index show foo2 
+INDEX-PROPERTY  VALUE                     
+name            foo2                      
+replicas        1                         
+shards          1                         
+created         2026-05-12 17:47:37       
+uuid            XmRtlh_JSreIzTB7jJNNJA    
+fields          id,message,time,title,user
+```
+
+Now, let's create a new index:
+
+```console
+$ esctl index create hyperdrive @timestamp:date message:keyword tag:text
+
+esctl index show hyperdrive 
+INDEX-PROPERTY  VALUE                 
+name            hyperdrive            
+replicas        1                     
+shards          1                     
+created         2026-06-24 10:16:23   
+uuid            gYfUj8TiR6aMB_BHmMYr3Q
+fields          @timestamp,message,tag
+```
+
+Once we have an index, we can insert documents into it (you'll need
+[gfn](https://codeberg.org/scip/gfn) for this):
+
+```console
+$ for name in $(gfn JapaneseNamesDiverse -n 20); do \
+     esctl doc add -i hyperdrive \
+     "{\"message\":\"$name\",\"tag\":\"loop\",\"@timestamp\":\"$(date
+     --iso-8601=second)\"}"; \
+     sleep 1; \
+  done

+2463257155346426021
+596556586001412147
+```
+
+Now, let's search them:
+
+```console
+$ esctl search -i hyperdrive -l 2 | jq
+{
+  "id": "2463257155346426021",
+  "score": 0.0000,
+  "index": "hyperdrive",
+  "source": {
+    "@timestamp": "2026-06-24T10:25:19+02:00",
+    "message": "inenen",
+    "tag": "loop"
+  }
+}
+{
+  "id": "596556586001412147",
+  "score": 0.0000,
+  "index": "hyperdrive",
+  "source": {
+    "@timestamp": "2026-06-24T10:25:20+02:00",
+    "message": "ominuhen",
+    "tag": "loop"
+  }
+}
+```
+
+There are also some uniq features which are not directly available via
+the ES API or GUI. Here's one example: say you have a number of
+indices with ILM policies each. At some day there were a surge in
+incoming data in some of them and you want to know, when the excess
+data will be rolled over to cold storage:
+
+```console
+$ esctl ilm forecast sh -f warm -w 3d 
+1.1 TB bytes of data in warm phase will be rolled within 72h0m0s to the next phase
+```
+
+You may also look at a detailed ilm forecast list:
+
+```console
+$ esctl ilm forecast ls -f warm -w 3d
+INDEX                           CURRENT-SIZE  CURRENT-AGE  VIRTUAL-AGE  MIN-AGE  MIN-SIZE  CURRENT-PHASE  NEXT-PHASE
+foobar-n1-p01-elastic-000126    12 GB         2d:8h:12m    3d:5h:16m    7d       25 GB     hot            warm

+foobar-n1-q01-misc-000072       18 GB         6d:15h:21m   4d:21h:36m   7d       25 GB     hot            warm      
+delaware-f1-p01-kafka-000023    1.3 MB        15h:12m      0s           7d       25 GB     hot            warm

+delaware-f1-q01-kafka-000023    1.5 MB        15h:12m      0s           7d       25 GB     hot            warm      
+delaware-f1-q01-misc-000024     16 GB         6d:15h:31m   4d:13h:52m   7d       25 GB     hot            warm      
+delaware-n1-p01-elastic-000417  16 GB         12h:42m      4d:10h:31m   7d       25 GB     hot            warm 
+```
+So you can see, which index will be rolled over when. Note the
+**VIRTUAL-AGE** field however: it is calculated from the current
+storage usage of the index in relation to rollover max shard size. So
+you can see, when an index will be rolled over either because it aged
+out or because its storage exceeded the limit.

+
+Please note, that `esctl` is still in its early stages and things are
+changing heavily every now and then. New commands are being added
+constantly as well.
