License Acquisition

Start with a free trial or obtain a temporary license to test all features. Consider purchasing a commercial license for full access.

Basic Initialization and Setup

Initialize your index as follows:

import com.groupdocs.search.Index;

public class GroupDocsSetup {
    public static void main(String[] args) {
        String indexFolder = "path/to/index/directory";
        Index index = new Index(indexFolder);
    }
}

Implementation Guide

Let’s break down the implementation into sections based on each boolean feature.

Combine terms using the AND operator to find documents containing all specified keywords.

Overview

AND search ensures a document contains multiple specific words, enhancing result relevance.

Implementation Steps

  1. Initialize Index

    String indexFolder = "YOUR_OUTPUT_DIRECTORY/BooleanSearch/OperatorAnd";
Index index = new Index(indexFolder);

  2. Index Documents

    String documentsFolder = "YOUR_DOCUMENT_DIRECTORY";
index.add(documentsFolder);

  3. Perform Text Query Search

    String query1 = "comfort AND promotion";
SearchResult result1 = index.search(query1);

  4. Perform Object Query Search

    import com.groupdocs.search.query.*;

SearchQuery wordQuery1 = SearchQuery.createWordQuery("comfort");
SearchQuery wordQuery2 = SearchQuery.createWordQuery("promotion");
SearchQuery andQuery = SearchQuery.createAndQuery(wordQuery1, wordQuery2);
SearchResult result2 = index.search(andQuery);

Use the OR operator to find documents containing at least one specified term.

Overview

OR search broadens results by finding any document that includes either term, useful for general searches.

Implementation Steps

  1. Initialize Index

    String indexFolder = "YOUR_OUTPUT_DIRECTORY/BooleanSearch/OperatorOr";
Index index = new Index(indexFolder);

  2. Index Documents

    String documentsFolder = "YOUR_DOCUMENT_DIRECTORY";
index.add(documentsFolder);

  3. Perform Text Query Search

    String query1 = "comfort OR neque";
SearchResult result1 = index.search(query1);

  4. Perform Object Query Search

    SearchQuery wordQuery1 = SearchQuery.createWordQuery("comfort");
SearchQuery wordQuery2 = SearchQuery.createWordQuery("neque");
SearchQuery orQuery = SearchQuery.createOrQuery(wordQuery1, wordQuery2);
SearchResult result2 = index.search(orQuery);

Exclude terms from your search results using the NOT operator.

Overview

NOT search filters out unwanted documents by specifying terms that should not appear in the results.

Implementation Steps

  1. Initialize Index

    String indexFolder = "YOUR_OUTPUT_DIRECTORY/BooleanSearch/OperatorNot";
Index index = new Index(indexFolder);

  2. Index Documents

    String documentsFolder = "YOUR_DOCUMENT_DIRECTORY";
index.add(documentsFolder);

  3. Perform Text Query Search

    String query1 = "sportsman AND NOT Kynynmound";
SearchResult result1 = index.search(query1);

  4. Perform Object Query Search

    SearchQuery wordQuery1 = SearchQuery.createWordQuery("sportsman");
SearchQuery wordQuery2 = SearchQuery.createWordQuery("Kynynmound");
SearchQuery notQuery = SearchQuery.createNotQuery(wordQuery2);
SearchQuery andQuery = SearchQuery.createAndQuery(wordQuery1, notQuery);
SearchResult result2 = index.search(andQuery);

Complex Boolean Queries

Combine AND, OR, and NOT operators to create intricate search queries for highly specific results.

Overview

Complex boolean searches allow crafting detailed queries that refine document retrieval significantly.

Implementation Steps

  1. Initialize Index

    String indexFolder = "YOUR_OUTPUT_DIRECTORY/BooleanSearch/ComplexQueries";
Index index = new Index(indexFolder);

  2. Index Documents

    String documentsFolder = "YOUR_DOCUMENT_DIRECTORY";
index.add(documentsFolder);

  3. Perform Text Query Search

    String query1 = "(sportsman AND favourable) AND NOT (Kynynmound OR Murray)";
SearchResult result1 = index.search(query1);

  4. Perform Object Query Search

    SearchQuery word1Query = SearchQuery.createWordQuery("sportsman");
SearchQuery word2Query = SearchQuery.createWordQuery("favourable");
SearchQuery andQuery = SearchQuery.createAndQuery(word1Query, word2Query);

SearchQuery word3Query = SearchQuery.createWordQuery("Kynynmound");
SearchQuery word4Query = SearchQuery.createWordQuery("Murray");
SearchQuery orQuery = SearchQuery.createOrQuery(word3Query, word4Query);
SearchQuery notQuery = SearchQuery.createNotQuery(orQuery);

SearchQuery rootQuery = SearchQuery.createAndQuery(andQuery, notQuery);
SearchResult result2 = index.search(rootQuery);

Practical Applications

Boolean searches are powerful tools with numerous real-world applications:

  1. Document Management Systems: Quickly locate relevant documents by combining multiple search terms.
  2. Legal Research: Filter out irrelevant case studies or legal texts using NOT queries.
  3. Customer Support: Enhance support ticket resolution by finding all tickets containing specific keywords (AND) while excluding certain phrases (NOT).
  4. Content Curation: Use OR searches to gather articles covering various topics.

Conclusion

By mastering boolean searches with GroupDocs.Search for Java, you can significantly enhance your document retrieval capabilities. Start implementing these techniques today and streamline your search processes.
