Basic Initialization and Setup

import com.groupdocs.search.Index;

// Define the index directory path
String indexFolder = "YOUR_OUTPUT_DIRECTORY/UpdateIndexedDocuments/Index";

// Create an Index instance
Index index = new Index(indexFolder);

Implementation Guide

Update Indexed Documents

Keeping your index in sync with source files is a core part of manage index versions java.

Step‑by‑Step Implementation

1. Define Directory Paths

String indexFolder = "YOUR_OUTPUT_DIRECTORY/UpdateIndexedDocuments/Index";
String documentFolder = "YOUR_DOCUMENT_DIRECTORY/Documents";

2. Prepare Data

Utils.cleanDirectory(documentFolder);
Utils.copyFiles(Utils.DocumentsPath, documentFolder);

3. Create an Index

Index index = new Index(indexFolder);

4. Add Documents to the Index

index.add(documentFolder);

5. Perform Initial Search

String query = "son";
SearchResult searchResult = index.search(query);

6. Simulate Document Changes

Utils.copyFiles(Utils.DocumentsPath4, documentFolder);

7. Set Update Options

UpdateOptions options = new UpdateOptions();
options.setThreads(2); // Using two threads for faster indexing

8. Update the Index

index.update(options);

9. Verify Updates with Another Search

SearchResult searchResult2 = index.search(query);

Troubleshooting Tips

  • Verify that all file paths are correct and accessible.
  • Ensure the process has read/write permissions on the index folder.
  • Monitor CPU and memory usage when increasing thread count.

Update Index Version

When you upgrade GroupDocs.Search, you may need to manage index versions java to keep existing indexes usable.

Step‑by‑Step Implementation

1. Define Directory Paths

String oldIndexFolder = Utils.OldIndexPath;
String sourceIndexFolder = "YOUR_DOCUMENT_DIRECTORY/SourceIndex";
String targetIndexFolder = "YOUR_OUTPUT_DIRECTORY/TargetIndex";

2. Prepare Data

Utils.cleanDirectory(sourceIndexFolder);
Utils.cleanDirectory(targetIndexFolder);
Utils.copyFiles(oldIndexFolder, sourceIndexFolder);

3. Create an Index Updater

IndexUpdater updater = new IndexUpdater();

4. Check and Update Version

if (updater.canUpdateVersion(sourceIndexFolder)) {
    VersionUpdateResult result = updater.updateVersion(sourceIndexFolder, targetIndexFolder);
}

Troubleshooting Tips

  • Confirm that the source index was created with a supported older version.
  • Ensure sufficient disk space for the target index folder.
  • Update all Maven dependencies to the same version to avoid compatibility issues.

Practical Applications

  1. Content Management Systems – Keep search indexes fresh as articles, PDFs, and images are added or edited.
  2. Legal Document Repositories – Automatically reflect amendments to contracts, statutes, and case files.
  3. Enterprise Data Warehousing – Regularly refresh indexed data for accurate analytics and reporting.

Performance Considerations

  • Thread Management – Use multi‑threading wisely; too many threads can cause GC pressure.
  • Memory Monitoring – Periodically call System.gc() or use profiling tools to watch heap usage.
  • Query Optimization – Write concise search strings and leverage filters to reduce result set size.

Frequently Asked Questions

Q: Can I upgrade an index created with a very old version of GroupDocs.Search?
A: Yes, as long as the old index is still readable by the library; the canUpdateVersion method will confirm compatibility.

Q: Do I need to recreate the index after every library update?
A: Not necessarily. Updating the index version is sufficient in most cases, saving time and resources.

Q: How many threads should I use for large indexes?
A: Start with 2‑4 threads and monitor CPU usage; increase only if the system has spare cores and memory.

Q: Is a trial license enough for production testing?
A: The trial license removes feature limits, making it ideal for development and QA environments.

Q: What happens to existing search results after an index version update?
A: The index structure is migrated, but the searchable content remains unchanged, so results stay consistent.
