Implementation Guide

Creating and Configuring an Index

An index is crucial as it enables efficient search operations on your documents. Here’s how you create and configure one:

Overview

This feature sets up a directory where your index will be stored, optimizing document retrieval processes.

Step-by-Step Guide

  1. Initialize the Index: Begin by specifying the directory for storing your index files.

    import com.groupdocs.search.Index;
    
    String indexFolder = "YOUR_DOCUMENT_DIRECTORY/AdvancedUsage/SearchForDifferentWordForms";
    Index index = new Index(indexFolder);
    
    • Explanation: The Index class initializes an indexing directory. Customize the path as per your environment setup.

Adding Documents to the Index

After configuring your index, add documents from a specified directory for search operations.

Overview

This step populates the index with documents from your chosen source directory.

Step-by-Step Guide

  1. Add Documents: Use the add method to include documents into the index.

    String documentsFolder = "YOUR_DOCUMENT_DIRECTORY/DocumentsPath";
    index.add(documentsFolder);
    
    • Explanation: The add function scans the specified directory and indexes all supported document formats. Ensure your paths are correctly set up for successful indexing.

Configuring Search Options

Configuring search options, such as enabling word forms search, enhances search capabilities significantly.

Overview

Setting search options allows you to tailor searches according to specific needs like finding grammatical variations of words.

Step-by-Step Guide

  1. Enable Word Forms Search: Configure the SearchOptions to include word form searching.

    import com.groupdocs.search.SearchOptions;
    
    SearchOptions options = new SearchOptions();
    options.setUseWordFormsSearch(true); // Enables search for different grammatical variations of words.
    
    • Explanation: The setUseWordFormsSearch(true) option allows the system to recognize and match various forms of a word, improving search accuracy.

With everything set up, it’s time to perform searches across your indexed documents using specified queries.

Overview

This feature conducts searches with customized options on the indexed data.

Step-by-Step Guide

  1. Execute Search: Implement the search functionality with a query and configured options.

    import com.groupdocs.search.SearchResult;
    
    String query = "wished";
    SearchResult result = index.search(query, options);
    
    • Explanation: The search method executes the query on the indexed documents using specified options. It returns a SearchResult object containing all matched entries.

Troubleshooting Tips

  • Ensure directory paths are correct and accessible.
  • Confirm that your Java environment is correctly set up to avoid runtime errors.
  • Verify that document formats are supported by GroupDocs.Search.
