Implementation Guide

This section covers each functionality in detail.

Creating and Indexing Documents

Overview

To perform efficient searches, first create an index for your documents to enable quick retrieval.

Step-by-Step Guide

  1. Specify Index Directory:
string indexFolder = "YOUR_DOCUMENT_DIRECTORY/AdvancedUsage/SearchResults";
  1. Create an Index Instance:
using GroupDocs.Search;

// Create an instance of Index at the specified folder
Index index = new Index(indexFolder);
  1. Add Documents to the Index:
// Add documents from a specific directory for searching
index.Add("YOUR_DOCUMENT_DIRECTORY");

Overview

Fuzzy search helps find approximate matches, accommodating minor errors or variations in your query.

Step-by-Step Guide

  1. Create Search Options:
using GroupDocs.Search.Options;

// Configure fuzzy search options
SearchOptions options = new SearchOptions();
options.FuzzySearch.Enabled = true; 
options.FuzzySearch.FuzzyAlgorithm = new TableDiscreteFunction(3);
  1. Define and Execute the Query:
string query = "water OR \"Lorem ipsum\"";

// Perform search using configured options
SearchResult result = index.Search(query, options);

Extracting and Displaying Search Results

Overview

After performing a search, extract relevant information from the results.

Step-by-Step Guide

  1. Iterate Over Each Document:
using GroupDocs.Search.Results;
using System;

for (int i = 0; i < result.DocumentCount; i++)
{
    FoundDocument document = result.GetFoundDocument(i);

    // Display details of each found field
    for (int j = 0; j < document.FoundFields.Length; j++)
    {
        FoundDocumentField field = document.FoundFields[j];

        if (field.Terms != null)
        {
            foreach (var term in field.Terms)
            {
                Console.WriteLine($"Term: {term}, Occurrences: {field.TermCount[term]}");
            }
        }

        if (field.TermSequences != null)
        {
            foreach (string sequence in field.TermSequences)
            {
                Console.WriteLine($"Sequence: {sequence}");
            }
        }
    }
}

Practical Applications

Explore real-world scenarios for these features:

  1. Legal Document Management: Quickly find case-related documents using fuzzy search.
  2. Healthcare Data Retrieval: Efficiently index and retrieve patient records with specific keywords.
  3. Academic Research: Search through extensive research papers for relevant topics or phrases.

Performance Considerations

To ensure optimal performance with GroupDocs.Search:

  • Optimize Indexing: Regularly update indexes to reflect the latest documents.
  • Resource Usage: Monitor memory and CPU usage during search operations.
  • Memory Management: Use efficient data structures and dispose of unneeded objects promptly.

Conclusion
