        Lupyne is a search engine based on [PyLucene](http://lucene.apache.org/pylucene/), the Python extension for accessing Java Lucene.
        Lucene is a relatively low-level toolkit, and PyLucene wraps it through automatic code generation.
        So although Java idioms are translated to Python idioms where possible, the resulting interface is far from Pythonic.
        See `./docs/examples.ipynb` for comparisons with the Lucene API.
        
        Lupyne also provides a RESTful JSON search server, based on [CherryPy](http://cherrypy.org).
        Note Solr and Elasticsearch are popular options for Lucene-based search, if no further (Python) customization is needed.
        So while the server is suitable for production usage, its primary motivation is to be an extensible example.
        
        Not having to initially choose between an embedded library and a server not only provides greater flexibility,
        it can provide better performance, e.g., batch indexing offline and remote searching live.
        Additionally only lightweight wrappers with extended behavior are used wherever possible,
        so falling back to using PyLucene directly is always an option, but should never be necessary for performance.
        
        # Usage
        PyLucene requires initializing the VM.
        
        ```python
        import lucene
        
        lucene.initVM()
        ```
        
        Indexes are accessed through an `IndexSearcher` (read-only), `IndexWriter`, or the combined `Indexer`.
        
        ```python
        from lupyne import engine
        
        searcher = engine.IndexSearcher('index/path')
        hits = searcher.search('text:query')
        ```
        
        Run the server.
        
            $ python -m lupyne.server
        
        Read the [documentation](http://lupyne.surge.sh).
        
        # Installation
        
            $ pip install lupyne[server]
