# Anserini: Experiments on [TREC 2017 CAR](http://trec-car.cs.unh.edu/) (v2.0)

## Indexing

Typical indexing command:

```
${index_cmds}
```

The directory `/path/to/Car17v2.0` should be the root directory of Complex Answer Retrieval (CAR) paragraph corpus (v2.0), which can be downloaded [here](http://trec-car.cs.unh.edu/datareleases/).

For additional details, see explanation of [common indexing options](common-indexing-options.md).

## Retrieval

The "benchmarkY1-test" topics and qrels are stored in `src/main/resources/topics-and-qrels/`, downloaded from [the CAR website](http://trec-car.cs.unh.edu/datareleases/):

+ `topics.car17v2.0.test.pages.cbor-hierarchical.txt`
+ `qrels.car17v2.0.test.pages.cbor-hierarchical.txt`


After indexing has completed, you should be able to perform retrieval as follows:

```
${ranking_cmds}
```

Evaluation can be performed using `trec_eval`:

```
${eval_cmds}
```

## Effectiveness

With the above commands, you should be able to replicate the following results:
