Implementation Guide

Feature 1: Creating and Managing Alphabet Dictionary

Overview

This feature enables you to create an alphabet dictionary, manage characters, and set specific character types for optimized document searches.

Step 1: Initialize Index
Index index = new Index(@"YOUR_DOCUMENT_DIRECTORY/Alphabet/Index");
Step 2: Clear Existing Alphabets
if (index.Dictionaries.Alphabet.Count > 0)
{
    index.Dictionaries.Alphabet.Clear();
}

Why: Ensure a fresh start by clearing any previous settings.

Step 3: Define Character Range

Add digits, capital letters, low line, and small letters to the alphabet dictionary.

List<char> list = new List<char>();
for (char i = (char)0x0030; i <= 0x0039; i++) 
{
    list.Add(i); // Digits
}
// Add more characters...
Step 4: Set Character Type to ‘Letter’
char[] characters = list.ToArray();
index.Dictionaries.Alphabet.SetRange(characters, CharacterType.Letter);

Why: This configuration ensures that searches consider these characters as part of a word.

Step 5: Update Hyphen Character Type
if (index.Dictionaries.Alphabet.GetCharacterType('-') != CharacterType.Blended)
{
    index.Dictionaries.Alphabet.SetRange(new char[] { '-' }, CharacterType.Blended);
}

Why: Treat hyphens as connectors between words for more accurate indexing.

Step 6: Export and Import Alphabet Dictionary
string fileName = @"YOUR_OUTPUT_DIRECTORY/Alphabet/Alphabet.dat";
index.Dictionaries.Alphabet.ExportDictionary(fileName);
index.Dictionaries.Alphabet.ImportDictionary(fileName);

Why: Enables persistence of your alphabet settings across sessions.

Feature 2: Indexing and Searching Documents

Overview

This feature demonstrates indexing documents in a specified folder and performing search operations using the created index.

Step 1: Add Documents to Index
string documentsFolder = @"YOUR_DOCUMENT_DIRECTORY";
index.Add(documentsFolder);

string query = "Elliot-Murray-Kynynmound";
SearchResult result = index.Search(query);

Why: Quickly locate relevant documents containing specific terms.

Practical Applications

  1. Legal Document Management: Streamline case file indexing for easy retrieval.
  2. Library Cataloging Systems: Enhance searchability of book titles and authors.
  3. Corporate Archives: Efficiently manage internal reports and communications.
  4. Customer Support Systems: Quickly access past interactions based on customer queries.

Performance Considerations

  • Optimize Index Size: Regularly prune unnecessary data to maintain performance.
  • Resource Usage: Monitor CPU and memory usage for efficient system operation.
  • Memory Management: Use best practices like disposing of objects after use in .NET applications.
