Sphinx Search is a full-text search engine that is focused on speed and scalability. It has a number of features such as distributed indexing, real-time indexing, and advanced query syntax. It also has a number of performance features such as caching, query optimization, and query logging.

Lucene is a text search engine library written in Java. It is designed to be fast and efficient, and it offers a number of features such as support for multiple languages, fuzzy search, and advanced query syntax. It also offers a number of performance features such as indexing and query optimization.

Example code

String queryString = "example query";

// Sphinx Search
SphinxClient sphinxClient = new SphinxClient();
sphinxClient.setQuery(queryString);
sphinxClient.runQuery();

// Lucene
Query query = new QueryParser("example", new StandardAnalyzer()).parse(queryString);
IndexSearcher searcher = new IndexSearcher(indexReader);
TopDocs results = searcher.search(query, 10);

Explanation:

• String queryString = "example query";: This line creates a string variable called queryString and assigns it the value of "example query".
• SphinxClient sphinxClient = new SphinxClient();: This line creates a SphinxClient object called sphinxClient.
• sphinxClient.setQuery(queryString);: This line sets the query string for the SphinxClient object.
• sphinxClient.runQuery();: This line runs the query on the SphinxClient object.
• Query query = new QueryParser("example", new StandardAnalyzer()).parse(queryString);: This line creates a Query object called query and sets it to the parsed query string using the QueryParser and StandardAnalyzer classes.
• IndexSearcher searcher = new IndexSearcher(indexReader);: This line creates an IndexSearcher object called searcher and sets it to the indexReader.
• TopDocs results = searcher.search(query, 10);: This line searches the index using the query object and returns the top 10 results in a TopDocs object called results.
