# sist2
sist2 (Simple incremental search tool)
*Warning: sist2 is in early development*
## Features
* Fast, low memory usage, multi-threaded
* Manage & schedule scan jobs with simple web interface (Docker only)
* Mobile-friendly Web interface

\*\*\* See [OCR](#ocr)
\*\*\*\* See [Named-Entity Recognition](#NER)
## Getting Started
### Using Docker Compose *(Windows/Linux/Mac)*
```yaml
version: "3"
services:
elasticsearch:
image: elasticsearch:7.17.9
restart: unless-stopped
volumes:
# This directory must have 1000:1000 permissions (or update PUID & PGID below)
- /data/sist2-es-data/:/usr/share/elasticsearch/data
environment:
- "discovery.type=single-node"
- "ES_JAVA_OPTS=-Xms2g -Xmx2g"
- "PUID=1000"
- "PGID=1000"
sist2-admin:
image: simon987/sist2:3.4.2-x64-linux
restart: unless-stopped
volumes:
- /data/sist2-admin-data/:/sist2-admin/
- /:/host
ports:
- 4090:4090
# NOTE: Don't expose this port publicly!
- 8080:8080
working_dir: /root/sist2-admin/
entrypoint: python3
command:
- /root/sist2-admin/sist2_admin/app.py
```
Navigate to http://localhost:8080/ to configure sist2-admin.
### Using the executable file *(Linux/WSL only)*
1. Choose search backend (See [comparison](#search-backends)):
* **Elasticsearch**: have an Elasticsearch (version >= 6.8.X, ideally >=7.14.0) instance running
1. Download [from official website](https://www.elastic.co/downloads/elasticsearch)
2. *(or)* Run using docker:
```bash
docker run -d -p 9200:9200 -e "discovery.type=single-node" elasticsearch:7.17.9
```
* **SQLite**: No installation required
2. 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`.
3. See [usage guide](docs/USAGE.md) for command line usage.
Example usage:
1. Scan a directory: `sist2 scan ~/Documents --output ./documents.sist2`
2. Prepare search index:
* **Elasticsearch**: `sist2 index --es-url http://localhost:9200 ./documents.sist2`
* **SQLite**: `sist2 sqlite-index --search-index ./search.sist2 ./documents.sist2`
3. Start web interface:
* **Elasticsearch**: `sist2 web ./documents.sist2`
* **SQLite**: `sist2 web --search-index ./search.sist2 ./documents.sist2`

\* *See [Archive files](#archive-files)*
### Archive files
**sist2** will scan files stored into archive files (zip, tar, 7z...) as if they were directly in the file system.
Recursive (archives inside archives)
scan is also supported.
**Limitations**:
* Support for parsing media files with formats that require *seek* (e.g. `.gif`, `.mp4` w/ fragmented metadata etc.)
is limitted (see `--mem-buffer` option)
* Archive files are scanned sequentially, by a single thread. On systems where
**sist2** is not I/O bound, scans might be faster when larger archives are split into smaller parts.
### OCR
You can enable OCR support for ebook (pdf,xps,fb2,epub) or image file types with the
`--ocr-lang ` option in combination with `--ocr-images` and/or `--ocr-ebooks`.
Download the language data files with your package manager (`apt install tesseract-ocr-eng`) or
directly [from Github](https://github.com/tesseract-ocr/tesseract/wiki/Data-Files).
The `simon987/sist2` image comes with common languages
(hin, jpn, eng, fra, rus, spa, chi_sim, deu, pol) pre-installed.
You can use the `+` separator to specify multiple languages. The language
name must be identical to the `*.traineddata` file installed on your system
(use `chi_sim` rather than `chi-sim`).
Examples:
```bash
sist2 scan --ocr-ebooks --ocr-lang jpn ~/Books/Manga/
sist2 scan --ocr-images --ocr-lang eng ~/Images/Screenshots/
sist2 scan --ocr-ebooks --ocr-images --ocr-lang eng+chi_sim ~/Chinese-Bilingual/
```
### Search backends
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.
| | SQLite | Elasticsearch |
|----------------------------------------------|:---------------------------------------------------:|:-------------------------------------------------------------------------------------------------------------------------------------:|
| Requires separate search engine installation | | ✓ |
| Memory footprint | ~20MB | >500MB |
| Query syntax | [fts5](https://www.sqlite.org/fts5.html) | [query_string](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#query-string-syntax) |
| Fuzzy search | | ✓ |
| Media Types tree real-time updating | | ✓ |
| Manual tagging | ✓ | ✓ |
| User scripts | ✓ | ✓ |
| Media Type breakdown for search results | | ✓ |
| Embeddings search | ✓ *O(n)* | ✓ *O(logn)* |
### NER
sist2 v3.0.4+ supports named-entity recognition (NER). Simply add a supported repository URL to
**Configuration** > **Machine learning options** > **Model repositories**
to enable it.
The text processing is done in your browser, no data is sent to any third-party services.
See [simon987/sist2-ner-models](https://github.com/simon987/sist2-ner-models) for more details.
