## Quick Start

### Prerequisites

- Java 21 or higher
- OpenSearch/Elasticsearch cluster (2.x+ recommended)
- Maven 3.8+ for building from source

### Installation

Add the dependency to your `pom.xml`:

```xml
<dependency>
    <groupId>org.codelibs.fess</groupId>
    <artifactId>fess-suggest</artifactId>

                throw new NullPointerException("tc");
            }
            // Exercise interaction with dependency for verification purposes
            // These methods do not throw and allow interaction checks.
            tc.getConfig();
            tc.getCredentials();

        // This test ensures that for a standard HTTP URL, openConnection wraps the connection
        // in an NtlmHttpURLConnection, using mock handlers to avoid dependency on system handlers.
        setupMockProtocolHandlers();
        URL url = new URL("http://example.com/resource");
        URLConnection connection = handler.openConnection(url);
