Implementation Guide

Configuring Stop Words

Overview: This feature allows you to configure index settings and disable the use of stop words, enhancing search accuracy.

Disabling Stop Words

// Disable the use of stop words
tsettings.setUseStopWords(false);
  • Parameters: The setUseStopWords method takes a boolean value.
  • Purpose: This setting enhances search results by considering all words in queries, including those typically ignored.

Creating and Configuring an Index

Overview: Create an index with specific settings to manage your documents effectively.

Defining Output Directory

import com.groupdocs.search.Index;

// Define the path to the output directory for indexing
String indexFolder = "YOUR_OUTPUT_DIRECTORY\\IndexingWithStopWords";

// Create an index at the specified location with the configured settings
Index index = new Index(indexFolder, settings);
  • Parameters: The index constructor takes a folder path and settings.
  • Purpose: Establishes a directory for storing indexed data.

Adding Documents to the Index

Overview: Add documents from your directories into the created index to make them searchable.

Specifying Document Directory

// Define the path to your document directory
String documentsFolder = "YOUR_DOCUMENT_DIRECTORY";

// Add all documents in the specified folder to the index
index.add(documentsFolder);
  • Parameters: The add method takes a folder path.
  • Purpose: Incorporates documents into the search index for querying.

Searching the Index

Overview: Perform searches on your indexed data with customized queries, including previously ignored stop words.

Performing a Search Query

import com.groupdocs.search.results.SearchResult;

// Define your search query
tString query = "on";

// Perform the search operation using the index and the specified query
SearchResult result = index.search(query);
  • Parameters: The search method takes a string query.
  • Purpose: Executes a search on indexed content, providing relevant results.

Practical Applications
