---------------------------------
Summary: Improve faceting performance
Key: BLUR-321
URL: https://issues.apache.org/jira/browse/BLUR-321
Project: Apache Blur
Issue Type: Bug
Components: Blur
Affects Versions: 0.2.0, 0.2.1, 0.2.2
Reporter: Tim Williams
The performance of a query with facets is relative to the number of documents
that match the user query - so queries that match lots of documents (e.g. *)
perform pretty terrible in an environment with lots of data. This is even if
the query and all facets are independently very fast.
To reproduce, create a large index with some term that's in most documents,
then query on that term with lots (~200) trivial term-based facets.
