Step 2 − Initialize the QueryParser object created with a standard analyzer having version information and index name on which this query is to be run. ![]() ![]() Follow these steps to create a QueryParser − QueryParser class parses the user entered input into Lucene understandable format query. We will now show you a step-wise approach and help you understand the indexing process using a basic example. IndexSearcher returns a TopDocs object which contains the search details along with document ID(s) of the Document which is the result of the search operation. Then we create a Query with a Term and make a search using IndexSearcher by passing the Query to the searcher. We first create Directory(s) containing indexes and then pass it to IndexSearcher which opens the Directory using IndexReader. IndexSearcher is one of the core components of the searching process. Following diagram illustrates the process and its use. In recent years Lucene has become exceptionally popular and is. Apache Lucene is a library that allows to organize a full-text search across multiple documents by the specified keywords. You could create a Lucene document for each company name (or even description and anything useful info as well) Document doc new Document () doc.add (new TextField ('text', 'BlueCross BlueShield', )) writer.addDocument (doc) After adding all companies, you could use.
