Basic Initialization and Setup

Create an Index instance, then add documents to be searchable:

import com.groupdocs.search.*;

String indexFolder = "YOUR_DOCUMENT_DIRECTORY/AdvancedUsage/ManagingDictionaries/SynonymDictionary/Index";
String documentsFolder = "YOUR_DOCUMENT_DIRECTORY/DocumentsPath2";

// Creating an index in the specified folder
Index index = new Index(indexFolder);

// Adding documents from a specific folder to the index
index.add(documentsFolder);

Jak přidat synonyma do vašeho vyhledávacího indexu

Creating an index is the foundation. Below we walk through the essential steps, each paired with the exact code you need.

Funkce 1: Vytvoření a indexování indexu

// Create an index in the specified folder
Index index = new Index(indexFolder);

// Add documents from the given folder to the index
index.add(documentsFolder);

Funkce 2: Získání synonym pro slovo

String[] synonyms = index.getDictionaries().getSynonymDictionary().getSynonyms("make");

Funkce 3: Získání skupin synonym

String[][] synonymGroups = index.getDictionaries().getSynonymDictionary().getSynonymGroups("make");

Funkce 4: Správa položek slovníku synonym

if (index.getDictionaries().getSynonymDictionary().getCount() > 0) {
    index.getDictionaries().getSynonymDictionary().clear();
}

String[][] newSynonymGroups = new String[][]{
    new String[] { "achieve", "accomplish", "attain", "reach" },
    new String[] { "accept", "take", "have" },
    new String[] { "improve", "better" }
};

index.getDictionaries().getSynonymDictionary().addRange(newSynonymGroups);

Funkce 5: Export synonym do souboru

String exportFilePath = "YOUR_OUTPUT_DIRECTORY/AdvancedUsage/ManagingDictionaries/SynonymDictionary/Synonyms.dat";
index.getDictionaries().getSynonymDictionary().exportDictionary(exportFilePath);

Funkce 6: Import synonym ze souboru

index.getDictionaries().getSynonymDictionary().importDictionary(exportFilePath);

Funkce 7: Provádění vyhledávání s podporou synonym

String query = "better";
SearchOptions options = new SearchOptions();
options.setUseSynonymSearch(true);

SearchResult result = index.search(query, options);

Jak vyhledávat se synonyma

By enabling setUseSynonymSearch(true), the engine automatically expands the query using the synonym dictionary you built or imported. This step is crucial for delivering richer results without changing the user’s search behavior.

Jak importovat slovník synonym

If you already have a .dat file prepared by another environment, simply call importDictionary(path). This is ideal for synchronizing dictionaries across development, staging, and production servers.

Jak spravovat skupiny synonym

Synonym groups let you treat a set of terms as a single logical entity. Adding, clearing, or retrieving groups is done through the SynonymDictionary API, as shown in the code snippets above.

Jak optimalizovat vyhledávací index

  • Pravidelně odstraňujte nepoužívané položky: Use clear() before bulk updates.
  • Upravte haldu JVM: Large dictionaries may require more memory.
  • Udržujte knihovnu aktuální: New releases contain performance improvements.

Praktické aplikace

  1. Systémy pro správu obsahu (CMS): Users find articles even when they use alternative terminology.
  2. E‑commerce platformy: Product searches become tolerant to synonyms like “laptop” vs. “notebook”.
  3. Úložiště dokumentů: Legal or medical archives benefit from domain‑specific synonym groups.

Úvahy o výkonu

  • Optimalizujte úložiště indexu: Periodically rebuild the index to remove stale data.
  • Spravujte využití paměti: Monitor heap consumption when loading large synonym files.
  • Pravidelné aktualizace: Stay on the latest GroupDocs.Search version for bug fixes and speed gains.

Závěr

You now have a complete, step‑by‑step roadmap for how to add synonyms, import synonym dictionary files, manage synonym groups, and search with synonyms using GroupDocs.Search for Java. Apply these techniques to boost relevance, improve user satisfaction, and keep your search index performing at its best.
