## Getting Started

There are 2 ways to try Fess. The first is to download and install yourself. The second is to use [Docker](https://www.docker.com/products/docker-engine).

### Download and Install/Run

  linking directly to the master branch. This ensures that links reference a
  specific point in time, rather than a document that may change over time.
  
  See here for guidance on getting permanent links to files: https://help.github.com/en/articles/getting-permanent-links-to-files
  
  Please use the following format for linking documentation:

### Setting Crawl Limits

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

        }

        this.totalCount += count - result[0];
        return rebalance();
      }

      // setting my count
      result[0] = elemCount;
      if (count == 0) {
        return deleteMe();
      }
      this.totalCount += count - elemCount;
      this.elemCount = count;
      return this;
    }

        } else if (count > 0 && result[0] == 0) {
          this.distinctElements++;
        }

        this.totalCount += count - result[0];
        return rebalance();
      }

      result[0] = elemCount;
      if (count == 0) {
        return deleteMe();
      }
      this.totalCount += count - elemCount;
      this.elemCount = count;
