# Sideloading How-To
|
|
|
|
(This document is a bit of a draft to get this down in writing
|
|
while it's still fresh in my head.)
|
|
|
|
Some websites are much larger than others, this includes
|
|
Wikipedia, Stack Overflow, and a few others. They are so
|
|
large they are impractical to crawl in the traditional fashion,
|
|
but luckily they make available data dumps that can be processed
|
|
and loaded into the search engine through other means.
|
|
|
|
## Sideloading a directory tree
|
|
|
|
For relatively small websites, ad-hoc side-loading is available directly from a
|
|
folder structure on the hard drive. This is intended for loading manuals,
|
|
documentation and similar data sets that are large and slowly changing.
|
|
|
|
A website can be archived with wget, like this
|
|
|
|
```bash
|
|
UA="search.marginalia.nu" \
|
|
DOMAIN="www.example.com" \
|
|
wget -nc -x --continue -w 1 -r -U ${UA} -A "html" ${DOMAIN}
|
|
```
|
|
|
|
After doing this to a bunch of websites, create a YAML file something like this:
|
|
|
|
```yaml
|
|
sources:
|
|
- name: jdk-20
|
|
dir: "jdk-20/"
|
|
domainName: "docs.oracle.com"
|
|
baseUrl: "https://docs.oracle.com/en/java/javase/20/docs"
|
|
keywords:
|
|
- "java"
|
|
- "docs"
|
|
- "documentation"
|
|
- "javadoc"
|
|
- name: python3
|
|
dir: "python-3.11.5/"
|
|
domainName: "docs.python.org"
|
|
baseUrl: "https://docs.python.org/3/"
|
|
keywords:
|
|
- "python"
|
|
- "docs"
|
|
- "documentation"
|
|
- name: mariadb.com
|
|
dir: "mariadb.com/"
|
|
domainName: "mariadb.com"
|
|
baseUrl: "https://mariadb.com/"
|
|
keywords:
|
|
- "sql"
|
|
- "docs"
|
|
- "mariadb"
|
|
- "mysql"
|
|
```
|
|
|
|
|parameter|description|
|
|
|----|----|
|
|
|name|Purely informative|
|
|
|dir|Path of website contents relative to the location of the yaml file|
|
|
|domainName|The domain name of the website|
|
|
|baseUrl|This URL will be prefixed to the contents of `dir`|
|
|
|keywords|These supplemental keywords will be injected in each document|
|
|
|
|
The directory structure corresponding to the above might look like
|
|
|
|
```
|
|
docs-index.yaml
|
|
jdk-20/
|
|
jdk-20/resources/
|
|
jdk-20/api/
|
|
jdk-20/api/[...]
|
|
jdk-20/specs/
|
|
jdk-20/specs/[...]
|
|
jdk-20/index.html
|
|
mariadb.com
|
|
mariadb.com/kb/
|
|
mariadb.com/kb/[...]
|
|
python-3.11.5
|
|
python-3.11.5/genindex-B.html
|
|
python-3.11.5/library/
|
|
python-3.11.5/distutils/
|
|
python-3.11.5/[...]
|
|
[...]
|
|
```
|
|
|
|
This yaml-file can be processed and loaded into the search engine through the
|
|
Actions view.
|
|
|
|
## Sideloading Wikipedia
|
|
|
|
For now, this workflow depends on using the conversion process from
|
|
[https://encyclopedia.marginalia.nu/](https://encyclopedia.marginalia.nu/)
|
|
to pre-digest the data. This is because it uses OpenZIM which has a
|
|
license that is incompatible with this project.
|
|
|
|
Build the [encyclopedia.marginalia.nu Code](https://github.com/MarginaliaSearch/encyclopedia.marginalia.nu)
|
|
and follow the instructions for downloading a ZIM file, and then run something like
|
|
|
|
```$./encyclopedia convert file.zim articles.db```
|
|
|
|
This db-file can be processed and loaded into the search engine through the
|
|
Actions view.
|
|
|
|
FIXME: It will currently only point to encyclopedia.marginalia.nu and not main Wikipedia,
|
|
this should be made configurable.
|
|
|
|
## Sideloading Stack Overflow/Stackexchange
|
|
|
|
Stackexchange makes dumps available on Archive.org. These are unfortunately on a format that
|
|
needs some heavy-handed pre-processing before they can be loaded. A tool is available for
|
|
this in [tools/stackexchange-converter](../code/tools/stackexchange-converter).
|
|
|
|
After running `gradlew dist`, this tool is found in `build/dist/stackexchange-converter`,
|
|
follow the instructions in the stackexchange-converter readme, and
|
|
convert the stackexchange xml.7z-files to sqlite db-files.
|
|
|
|
A directory with such db-files can be processed and loaded into the
|
|
search engine through the Actions view. |
