    <p>I want to do a search for a query within a file "fdictionary.txt" containing a list of words (230,000 words) written line by line. any suggestion why this code is not working? The spell checking part is working and gives me the list of suggestions (I limited the length of the list to 1). what I want to do is to search that fdictionary and if the word is already in there, do not call spell checking. My Search function is not working. It does not give me error! Here is what I have implemented:</p> <pre><code>public class SpellCorrection { public static File indexDir = new File("/../idxDir"); public static void main(String[] args) throws IOException, FileNotFoundException, CorruptIndexException, ParseException { Directory directory = FSDirectory.open(indexDir); SpellChecker spell = new SpellChecker(directory); IndexWriterConfig config = new IndexWriterConfig(Version.LUCENE_20, null); File dictionary = new File("/../fdictionary00.txt"); spell.indexDictionary(new PlainTextDictionary(dictionary), config, true); String query = "red"; //kne, console String correctedQuery = query; //kne, console if (!search(directory, query)) { String[] suggestions = spell.suggestSimilar(query, 1); if (suggestions != null) {correctedQuery=suggestions[0];} } System.out.println("The Query was: "+query); System.out.println("The Corrected Query is: "+correctedQuery); } public static boolean search(Directory directory, String queryTerm) throws FileNotFoundException, CorruptIndexException, IOException, ParseException { boolean isIn = false; IndexReader indexReader = IndexReader.open(directory); IndexSearcher indexSearcher = new IndexSearcher(indexReader); Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_20); Term term = new Term(queryTerm); Query termQuery = new TermQuery(term); TopDocs hits = indexSearcher.search(termQuery, 100); System.out.println(hits.totalHits); if (hits.totalHits &gt; 0) { isIn = true; } return isIn; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
