copied!<p>Can you recommend a full-text search engine? (Preferably open source)</p> <p>I have a database of many (though relatively short) HTML documents. I want users to be able to search this database by entering one or more search words in my C++ desktop application. Hence, I’m looking for a fast full-text search solution to integrate with my app. Ideally, it should:</p> <ul> <li>Skip common words, such as <code>the</code>, <code>of</code>, <code>and</code>, etc.</li> <li>Support stemming, i.e. search for <code>run</code> also finds documents containing <code>runner</code>, <code>running</code> and <code>ran</code>.</li> <li>Be able to update its index in the background as new documents are added to the database.</li> <li>Be able to provide search word suggestions (like Google Suggest)</li> <li>Have a well-documented API</li> </ul> <p>To illustrate, assume the database has just two documents:</p> <blockquote> <p><em>Document 1</em>: <code>This is a test of text search.</code></p> <p><em>Document 2</em>: <code>Testing is fun.</code></p> </blockquote> <p>The following words should be in the index: <code>fun</code>, <code>search</code>, <code>test</code>, <code>testing</code>, <code>text</code>. If the user types <code>t</code> in the search box, I want the application to be able to suggest <code>test</code>, <code>testing</code> and <code>text</code> (Ideally, the application should be able to query the search engine for the 10 most common search words starting with <code>t</code>). A search for <code>testing</code> should return both documents.</p> <p>Other points:</p> <ul> <li>I don't need multi-user support</li> <li>I don't need support for complex queries</li> <li>The database resides on the user's computer, so the indexing should be performed locally. </li> </ul> <p>Can you suggest a C or C++ based solution? (I’ve briefly reviewed <a href="http://clucene.sourceforge.net/" rel="nofollow noreferrer">CLucene</a> and <a href="http://xapian.org" rel="nofollow noreferrer">Xapian</a>, but I’m not sure if either will address my needs, especially querying the search word indexes for the suggest feature).</p>

Querying!
