Simple search engine

# Installing

It is recommended to use [virtualenv](https://virtualenv.pypa.io).

```
pip install -r requirements.txt
```

## Testing

If you just want to test and don't want to install a PostgreSQL database
but have Docker installed, juste use the `docker-compose.yml`.

This is only for test, don't use this shit on production (the docker-compose
file)!

## Sphinx-search / Manticore-search

You can use [Sphinx-search](http://sphinxsearch.com/) but it's recommand to use
[Manticore-search](https://manticoresearch.com/) since the last version of
Sphinx-search is ditribued in closed-source instead of open-source (for
version 3.x).

All explication is for Manticore-search for the moment but at many time the
term `sphinx` is used in code because Manticore-search want to keep a
compatibility with Sphinx-search.

# Configuration

## Database

The database used for this project is PostgreSQL, you can update login
information in `config.py` file.

## Sphinx-search / Manticore-search

The configuration for this is in `sphinx_search.conf` file. For update this
file please view documentation of
[Sphinx-search](http://sphinxsearch.com/docs/manual-2.3.2.html) or
[Manticore-search](https://docs.manticoresearch.com).
Keep in mind you must keep up to date the file `config.py` in accordance with
the `sphinx_search.conf` file.

# Crawling

For now there is an example spider with neodarz website.
For launch all the crawler use the following command:

```
python app.py crawl
```

# Indexing

Before lauch indexing or searching command you must verifiy that the folder of
`path` option is present in your system (Warning: the last word of the `path`
option is the value of the `source` option, don't create this folder but only
his parent folder).

Example with the configuration for the indexer `datas`:

```
index neodarznet {
    source = neodarznet
    path = /tmp/data/neodarznet
}
```
Here the folder is `/tmp/data/`

The command for indexing is:
```
indexer --config sphinx_search.conf --all
```

Don't forget to launch the crawling command before this ;)

# Searching

Before you can make search, you must lauch the search server
```
searchd -c sphinx_search.conf
```

## Enjoy

You can now launch the server!

```
python app.py
```

For start searching send `GET` request to the following adresse (without `<` and
`>`):
```
127.0.0.1:5000/?search=<search terms>&index=<indexed website>
```

Resultat are in json format. If you whant to know witch website is indexed,
search in the file [sphinx_search.conf](https://git.khaganat.net/neodarz/khanindexer/blob/master/sphinx_search.conf)
all the line who start by `index`.
