### URL Filtering

```java
// Include patterns

        crawler.crawlerContext.setMaxThreadCheckCount(3);
        // crawler.crawlerContext.setMaxAccessCount(maxCount);
        crawler.crawlerContext.setNumOfThread(numOfThread);
        crawler.crawlerContext.setMaxDepth(1);
        crawler.urlFilter.addInclude(url + ".*");
        final String sessionId = crawler.execute();
        assertEquals(maxCount, dataService.getCount(sessionId));
        dataService.delete(sessionId);
    }

        crawler.crawlerContext.setMaxThreadCheckCount(3);
        // crawler.robotContext.setMaxAccessCount(maxCount);
        crawler.crawlerContext.setNumOfThread(numOfThread);
        crawler.crawlerContext.setMaxDepth(1);
        crawler.urlFilter.addInclude(url + ".*");
        final String sessionId = crawler.execute();
        assertEquals(maxCount, dataService.getCount(sessionId));
        dataService.delete(sessionId);
    }

    }

    /**
     * Sets the maximum depth for nested structure extraction.
     *
     * @param maxDepth the maximum depth
     */
    public void setMaxDepth(final int maxDepth) {
        this.maxDepth = maxDepth;
    }

    /**
     * Sets the field separator for key-value pairs.
     *
     * @param fieldSeparator the field separator
     */

// Exclude patterns (must not match)
crawler.urlFilter.addExclude(".*\\.(css|js|png|jpg)$");
```

### Setting Crawl Limits

```java
context.setMaxAccessCount(1000);  // Max URLs (0 = unlimited)
context.setMaxDepth(3);           // Max depth (-1 = unlimited)
context.setNumOfThread(10);       // Concurrent threads
```

### Accessing Results

```java
DataService ds = container.getComponent("dataService");

        crawlerContext.maxThreadCheckCount = maxThreadCheckCount;
    }

    /**
     * Sets the maximum depth.
     * @param maxDepth The maximum depth.
     */
    public void setMaxDepth(final int maxDepth) {
        crawlerContext.maxDepth = maxDepth;
    }

    /**
     * Sets the maximum access count.
     * @param maxAccessCount The maximum access count.
     */
