Locate the section for your github remote in the .git/config
file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = git@github.com:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

* Design Overview: | |
* In this implementation, the limit order book is represented using | |

* Each entry in this array corresponds to a specific price point and holds | |
* an instance of struct pricePoint. This data structure maintains a list |

If you want, I can try and help with pointers as to how to improve the indexing speed you get. Its quite easy to really increase it by using some simple guidelines, for example: | |
- Use create in the index API (assuming you can). | |
- Relax the real time aspect from 1 second to something a bit higher (index.engine.robin.refresh_interval). | |
- Increase the indexing buffer size (indices.memory.index_buffer_size), it defaults to the value 10% which is 10% of the heap. | |
- Increase the number of dirty operations that trigger automatic flush (so the translog won't get really big, even though its FS based) by setting index.translog.flush_threshold (defaults to 5000). | |
- Increase the memory allocated to elasticsearch node. By default its 1g. | |
- Start with a lower replica count (even 0), and then once the bulk loading is done, increate it to the value you want it to be using the update_settings API. This will improve things as possibly less shards will be allocated to each machine. | |
- Increase the number of machines you have so |
