Implementation Guide

Creating and Indexing Documents

Overview This feature demonstrates how to efficiently organize documents by creating an index for a folder containing multiple files.

Step 1: Define Paths

string indexFolder = "YOUR_DOCUMENT_DIRECTORY/ObtainSearchResultInformation";
string documentFolder = "YOUR_DOCUMENT_DIRECTORY/DocumentsPath";

// Create an instance of the Index class.
Index index = new Index(indexFolder);

// Add documents from the specified folder to the index.
index.Add(documentFolder);

Fuzzy Search Setup and Execution

Overview Fuzzy search allows you to find documents even with minor discrepancies in the search terms. This feature showcases setting up a fuzzy search with adjustable accuracy.

using GroupDocs.Search.Options;

SearchOptions options = new SearchOptions();
options.FuzzySearch.Enabled = true;
options.FuzzySearch.FuzzyAlgorithm = new TableDiscreteFunction(3); // Allow up to 3 differences

// Execute the search with fuzzy logic.
SearchResult result = index.Search("favourable OR \"ipsum dolor\"", options);

Console.WriteLine("Documents: " + result.DocumentCount);
Console.WriteLine("Total occurrences: " + result.OccurrenceCount);

Highlight Search Results in HTML Format

Overview Highlighting search results visually marks relevant sections within a file, facilitating quick analysis.

Step 1: Set Up High Compression

using GroupDocs.Search.Highlighters;
using GroupDocs.Search.Options;

IndexSettings settings = new IndexSettings();
settings.TextStorageSettings = new TextStorageSettings(Compression.High);

// Create an instance of the Index.
Index index = new Index(indexFolder, settings);
index.Add(documentFolder);

Step 2: Highlight and Output

SearchResult result = index.Search("solicitude");

if (result.DocumentCount > 0)
{
    FoundDocument document = result.GetFoundDocument(0);

    string path = "YOUR_OUTPUT_DIRECTORY/Highlighted.html";
    OutputAdapter outputAdapter = new FileOutputAdapter(OutputFormat.Html, path);
    Highlighter highlighter = new DocumentHighlighter(outputAdapter);

    // Generate highlighted HTML content.
    index.Highlight(document, highlighter);
}

Troubleshooting Tips

  • Ensure paths are correctly specified to avoid file not found errors.
  • Verify that all necessary permissions for read/write operations on directories are set.

Practical Applications

  1. Legal Document Review: Quickly locate specific case-related terms in large volumes of legal documents.
  2. Academic Research: Efficiently search through academic papers and journals for relevant research topics.
  3. Business Intelligence: Enhance data-driven decisions by searching key business metrics within reports.
  4. Customer Support: Expedite issue resolution by searching customer inquiries for common issues.
  5. Content Management Systems (CMS): Improve content retrieval in CMS platforms with fuzzy search capabilities.

Performance Considerations

  • Optimize index storage settings to balance speed and disk usage.
  • Regularly update indexes to ensure data is current, reducing unnecessary processing.
  • Manage resources efficiently by disposing of unused objects promptly to prevent memory leaks.
