 ## Getting Started
 
-1. Have an Elasticsearch (>= 6.8.X, ideally >=7.14.0) instance running
-    1. Download [from official website](https://www.elastic.co/downloads/elasticsearch)
-    1. *(or)* Run using docker:
-        ```bash
-        docker run -d -p 9200:9200 -e "discovery.type=single-node" elasticsearch:7.14.0
-        ```
-    1. *(or)* Run using docker-compose:
-        ```yaml
-          elasticsearch:
-            image: docker.elastic.co/elasticsearch/elasticsearch:7.14.0
-            environment:
-              - discovery.type=single-node
-              - "ES_JAVA_OPTS=-Xms1G -Xmx2G"
-        ```
-1. Download sist2 executable
-    1. Download the [latest sist2 release](https://github.com/simon987/sist2/releases). 
-Select the file corresponding to your CPU architecture and mark the binary as executable with `chmod +x` *
-    2. *(or)* Download a [development snapshot](https://files.simon987.net/.gate/sist2/simon987_sist2/) *(Not
-       recommended!)*
-    3. *(or)* `docker pull simon987/sist2:2.12.1-x64-linux`
+### Using Docker Compose *(Windows/Linux/Mac)*
 
-1. See [Usage guide](docs/USAGE.md)

+sist2 v3.0.7+ supports SQLite search backend. The SQLite search backend has
+fewer features and generally comparable query performance for medium-size
+indices, but it uses much less memory and is easier to set up.

-## Scan
+#### Thumbnail database size estimation
 
-### Scan options
+See chart below for rough estimate of thumbnail size vs. thumbnail size & quality arguments:
 
-* `-t, --threads` 
-      Number of threads for file parsing. **Do not set a number higher than `$(nproc)` or `$(Get-CimInstance Win32_ComputerSystem).NumberOfLogicalProcessors` in Windows!**
-* `--mem-throttle`
-    Total memory threshold in MiB for scan throttling. Worker threads will not start a new parse job
-    until the total memory usage of sist2 is below this threshold. Set to 0 to disable. DEFAULT=0
-* `-q, --thumbnail-quality` 
-    Thumbnail quality, on a scale of 1.0 to 31.0, 1.0 being the best.
-* `--thumbnail-size` 
-    Thumbnail size in pixels.
-* `--thumbnail-count`
-    Maximum number of thumbnails to generate. When set to a value >= 2, thumbnails for video previews
-    will be generated. The actual number of thumbnails generated depends on the length of the video (maximum 1 image 
-    every ~7s). Set to 0 to completely disable thumbnails.
-* `--content-size` 
-    Number of bytes of text to be extracted from the content of files (plain text, PDFs etc.).
-    Repeated whitespace and special characters do not count toward this limit.
-    Set to 0 to completely disable content parsing.
-* `--incremental`
-    Specify an existing index. Information about files in this index that were not modified (based on *mtime* attribute)
-    will be copied to the new index and will not be parsed again.
-* `-o, --output` Output directory. 
-* `--rewrite-url` Set the `rewrite_url` option for the web module (See [rewrite_url](#rewrite_url)) 
-* `--name` Set the `name` option for the web module
-* `--depth` Maximum scan dept. Set to 0 only scan files directly in the root directory, set to -1 for infinite depth
-* `--archive` Archive file mode.
-    * skip: Don't parse
-    * list: Only get file names as text
-    * shallow: Don't parse archives inside archives.
-    * recurse: Scan archives recursively (default)
-* `--ocr-lang`, `--ocr-ebooks`, `--ocr-images` See [OCR](../README.md#OCR)
-* `-e, --exclude` Regex pattern to exclude files. A file is excluded if the pattern matches any 
-    part of the full absolute path.
-    
-    Examples: 
-    * `-e ".*\.ttf"`: Ignore ttf files
-    * `-e ".*\.(ttf|rar)"`: Ignore ttf and rar files
-    * `-e "^/mnt/backups/"`: Ignore all files in the `/mnt/backups/` directory
-    * `-e "^/mnt/Data[12]/"`: Ignore all files in the `/mnt/Data1/` and `/mnt/Data2/` directory
-    * `-e "(^/usr/)|(^/var/)|(^/media/DRIVE-A/tmp/)|(^/media/DRIVE-B/Trash/)"` Exclude the
-     `/usr`, `/var`, `/media/DRIVE-A/tmp`, `/media/DRIVE-B/Trash` directories
-* `--fast` Only index file names and mime type
-* `--treemap-threshold` Directories smaller than (`treemap-threshold` * `<total size of the index>`)
-    will not be considered for the disk utilisation visualization; their size will be added to
-    the parent directory. If the parent directory is still smaller than the threshold, it will also be "merged upwards"
-    and so on.
-    
-    In effect, smaller `treemap-threshold` values will yield a more detailed 
-    (but also a more cluttered and harder to read) visualization. 
-    
-* `--mem-buffer` Maximum memory buffer size in MiB (per thread) for files inside archives. Media files 
-    larger than this number will be read sequentially and no *seek* operations will be supported.
+For example, `--thumbnail-size=500`, `--thumbnail-quality=50` for a directory with 8 million images will create a thumbnail database 
+that is about `8000000 * 11.8kB = 94.4GB`.
 
-    To check if a media file can be parsed without *seek*, execute `cat file.mp4 | ffprobe -`
-* `--read-subtitles` When enabled, will attempt to read the subtitles stream from media files.
-* `--fast-epub` Much faster but less accurate EPUB parsing. When enabled, sist2 will use a simple HTML parser to read epub files instead of the MuPDF library. No thumbnails are generated and author/title metadata are not parsed.
-* `--checksums` Calculate file checksums (SHA1) when scanning files. This option does not cause any additional read 
-  operations. Checksums are not calculated for all file types, unless the file is inside an archive. When enabled, duplicate
-  files are hidden in the web UI (this behaviour can be toggled in the Configuration page).

-### Index format
-
-A typical `ndjson` type index structure looks like this:
-```
-documents.idx/
-├── descriptor.json
-├── _index_main.ndjson.zst
-├── treemap.csv
-├── agg_mime.csv
-├── agg_date.csv
-├── add_size.csv

-├── tags/
-|   ├── data.mdb
-|   └── lock.mdb
-└── meta/
-    ├── data.mdb
-    └── lock.mdb
-```
-
-The `_index_*.ndjson.zst` files contain the document data in JSON format, in a compressed newline-delemited file.
-
-The `thumbs/` folder is a [LMDB](https://en.wikipedia.org/wiki/Lightning_Memory-Mapped_Database)
-database containing the thumbnails.
-
-The `descriptor.json` file contains general information about the index. The 
-following fields are safe to modify manually: `root`, `name`, [rewrite_url](#rewrite_url) and `timestamp`.
-
-The `.csv` are pre-computed aggregations necessary for the stats page.
-
-*thumbs/*:
-
-LMDB key-value store. Keys are **binary** 16-byte md5 hash* (`_id` field)
-and values are raw image bytes.
-
-*\* Hash is calculated from the full path of the file, including the extension, relative to the index root*

-## Index
-### Index options
- * `--es-url` 
- Elasticsearch url and port. If you are using docker, make sure that both containers are on the
- same network.
- * `--es-index` 
-    Elasticsearch index name. DEFAULT=sist2
- * `-p, --print` 
-    Print index in JSON format to stdout.
- * `--incremental-index`
-   Conduct incremental indexing. Assumes that the old index is already ingested in Elasticsearch.
-   Only the new changes since the last scan will be sent.
- * `--script-file` 
-    Path to user script. See [Scripting](scripting.md).
- * `--mappings-file`
-    Path to custom Elasticsearch mappings. If none is specified, [the bundled mappings](https://github.com/simon987/sist2/tree/master/schema) will be used.
- * `--settings-file`
-    Path to custom Elasticsearch settings. *(See above)*
- * `--async-script` 
-    Use `wait_for_completion=false` elasticsearch option while executing user script.
-     (See [Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/tasks.html))
- * `--batch-size=<int>` 
-    Index batch size. Indexing is generally faster with larger batches, but payloads that
-    are too large will fail and additional overhead for retrying with smaller sizes may slow
-    down the process.
- * `-f, --force-reset` 
-    Reset Elasticsearch mappings and settings.
- * `-t, --threads` Number of threads to use. Ideally, choose a number equal to the number of logical cores of the machine hosting Elasticsearch.
-
