Hey @lintool, am looking to add some topic files to anserini so we can do a 2CR. These are json files that follow the DefaultQueryIterator format, so basically:

{"<id>": {"title": "<some text>"}, ....}

Which anserini TopicReader would work for this sort of topic file? Let me know and I'll add a corresponding PR in anserini as well.

For reference, I'm following this PR as a guide on how to add topics to anserini.

Take a look here? https://github.com/castorini/anserini/tree/master/src/main/java/io/anserini/search/topicreader

Maybe this one? https://github.com/castorini/anserini/blob/master/src/main/java/io/anserini/search/topicreader/JsonStringTopicReader.java

Looks good. Just need to change a few names to align the paper:

1. Eval settings: validation -> small
2. A column to show the query set we used in the table: val queries
