Greetings,

There is something very simple we wish to achieve but we're finding it a bit difficult to find any information on how to do so, but we're sure it's possible.

Basically we want to be able to return all entities in the index. If we pass an empty say, BooleanQuery, or empty WildcardQuery, we get zero results.

Any pointers on how we can do this?

Hi,

Lucene contains a MatchAllDocsQuery. This should do the trick. Otherwise you could index a constant field/value for each entity and query for this value.
I am not sure what you usecase is, but be aware of memory usage. I don't recommend to load all entities in one go. That will not scale for large indexes.

Thanks Hardy - this is exactly what we need.

We don't want to load all entities per se, we'll allow the user to page through the results.
