How to Search Documents Java – Feature 1: Extract Search Result Information

Overview

Extracting detailed information (terms, phrases, occurrence counts) helps you build analytics dashboards or generate reports about the content of your document set.

Step‑by‑Step Implementation

Step 1: Create an Index

String indexFolder = YOUR_DOCUMENT_DIRECTORY + "/ObtainSearchResultInformation";
Index index = new Index(indexFolder);
index.add(documentFolder);

SearchOptions options = new SearchOptions();
options.getFuzzySearch().setEnabled(true);
options.getFuzzySearch().setFuzzyAlgorithm(new TableDiscreteFunction(3));

String query = "favourable OR \"ipsum dolor\"";
SearchResult result = index.search(query, options);

Step 4: Extract Occurrences

for (int i = 0; i < result.getDocumentCount(); i++) {
    FoundDocument document = result.getFoundDocument(i);
    for (FoundDocumentField field : document.getFoundFields()) {
        if (field.getTerms() != null) {
            for (String term : field.getTerms()) {
                int occurrences = field.getTermsOccurrences()[field.getTerms().indexOf(term)];
                System.out.println("Term: " + term + ", Occurrences: " + occurrences);
            }
        }
        if (field.getTermSequences() != null) {
            for (String[] terms : field.getTermSequences()) {
                int occurrences = field.getTermSequencesOccurrences()[ArrayUtils.indexOf(field.getTermSequences(), terms)];
                StringBuilder sequence = new StringBuilder();
                for (String term : terms) {
                    sequence.append(term).append(" ");
                }
                System.out.println("Phrase: " + sequence.toString() + ", Occurrences: " + occurrences);
            }
        }
    }
}

Feature 2: Highlight Search Terms Java in Documents

Overview

Generating an HTML file with highlight search terms java lets end‑users instantly see where matches appear, improving review speed and collaboration.

Step‑by‑Step Implementation

Step 1: Set Up Index with High Compression

String indexFolder = YOUR_DOCUMENT_DIRECTORY + "/HighlightSearchResults";
IndexSettings settings = new IndexSettings();
settings.setTextStorageSettings(new TextStorageSettings(Compression.High));
Index index = new Index(indexFolder, settings);
index.add(documentFolder);

Step 2: Perform Search and Highlight Results

SearchResult result = index.search("solicitude");
if (result.getDocumentCount() > 0) {
    FoundDocument document = result.getFoundDocument(0);
    String path = YOUR_OUTPUT_DIRECTORY + "/Highlighted.html";
    OutputAdapter outputAdapter = new FileOutputAdapter(OutputFormat.Html, path);
    Highlighter highlighter = new DocumentHighlighter(outputAdapter);
    index.highlight(document, highlighter);
}

Practical Applications

  1. Legal Document Review – Quickly locate clauses across hundreds of contracts.
  2. Academic Research – Extract key phrases from research papers for literature reviews.
  3. Customer Support – Identify recurring issues in email archives.
  4. Content Management – Highlight keywords in articles and blogs for SEO audits.

Performance Considerations

  • Compression: High compression reduces storage but may increase CPU usage; test for your workload.
